Hi @Dave CCleaner: I don't know how other users would feel about this, but why doesn't Avast/Piriform just create a trimmed-down Portable build without all the "extra" features likes Software Updater, PC Health Check, Performance Optimizer, etc.? If users absolutely need those extra features they always have the option to install the full CCleaner program on their hard drive. As far as I know all Avast/Piriform needs to provide to run the core features of CCleaner Portable are four files - CCleaner.exe, CCleaner 64.exe, License.txt (required for legal purposes only, I assume) and portable.dat plus the \lang folder for non-English users as shown below. As long as the ccleaner.ini file is automatically generated the first time that the CCleaner.exe or CCleaner64.exe executable is launched (which it does by default) I think that's all that's really required for users who just want to use CCleaner Portable for a deep disk clean. Is there a Portable build of CCleaner Pro / Pro Plus that includes extra features like Software Updater, etc. that Avast/Piriform is legally obligated to offer to customers with a paid subscription? ----------------- 64-bit Win 10 Pro v21H2 build 19044.1826 * Firefox v103.0.0 * Microsoft Defender v4.18.2205.7-1.1.19400.3 * Malwarebytes Premium v4.5.12.204-1.0.1725 * Macrium Reflect Free v8.0.6867 * CCleaner Free Portable v5.91.9537 Dell Inspiron 15 5584, Intel i5-8265U CPU, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G NVMe SSD, Intel UHD Graphics 620

Hi OLLI_S: Please see my 20-Jun-2022 response in CCleaner 6.00/6.01 Portable Not Available to employee Dave CCleaner's comments on this subject. We were told in October 2019 that the portable builds of Speccy, Defraggler and Recuva would be "reestablished shortly" on their respective builds pages (e.g., at https://www.ccleaner.com/speccy/builds for Speccy) but those download links are still missing, in spite of Piriform's insistence that these portable builds "have not died". The situation with CCleaner Portable is a bit different because Piriform is still posting a ccsetup591.zip file on the CCleaner builds page at https://www.ccleaner.com/ccleaner/builds. The only major issue with CCleaner Portable is that the recommended ccsetup591.zip was released back in March 2022 and will continue to be a few versions behind the "standard" CCleaner installer until Piriform fixes the buggy file structure in CCleaner Portable. That will hopefully occur when the upcoming CCleaner v6.03 is released next month. ---------------- 64-bit Win 10 Pro v21H2 build 19044.1826 * Firefox v102.0.1 * Microsoft Defender v4.18.2205.7-1.1.19400.3 * Malwarebytes Premium v4.5.11.202-1.0.1716 * Macrium Reflect Free v8.0.6867 * CCleaner Free Portable v5.91.9537 Dell Inspiron 15 5584, Intel i5-8265U CPU, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G NVMe SSD, Intel UHD Graphics 620

Hi LeshaRB: There is a better discussion about this in mogli's April 22 thread 5.92 portable broken [download 5.91 from website] in the CCleaner Bug Reporting board. Moderator Andavari's 06-Jun-2022 posted <here> in that thread that "Where you unzipped CCleaner Portable make sure the portable.dat file is in the same folder as CCleaner.exe and CCleaner64.exe, it's required so it knows to not create registry data..." If you look at the folder structure of the recommended ccsetup591.zip file you will see that CCleaner.exe and CCleaner64.exe are located in the "root" folder with portable.dat. If you double-click on CCleaner.exe (if you have a 32-bit OS) or CCleaner64.exe (if you have a 64-bit OS) it will not create the unwanted (and unnecessary) scheduled tasks and registry entries I showed <here> in mogli's thread. If built correctly, a CCleaner Portable app that can be run from a removable USB thumb drive on different computers should not be making changes to the Windows registry when it is launched. Instead, all custom configuration settings should be stored in the ccleaner.ini file that is created the first time you run CCleaner.exe or CCleaner64.exe. If you use the buggy ccsetup601.zip file that you downloaded from a third-party site that now has the CCleaner.exe and CCleaner64.exe in the wrong locations and you don't fix this yourself then you will add all sorts of garbage in your Windows registry and create scheduled tasks in Task Scheduler that won't run properly the first time you launch CCleaner. That is the danger of downloading CCleaner from third-party sites - you should always use the recommended version posted on the official builds page at https://www.ccleaner.com/ccleaner/builds. __________________________________________ Kudo's to Moderator hazelnut, who pointed out that if you scroll to the bottom of the release notes for CCleaner 6.02.9938 (rel. 20-Jul-2022) at https://www.ccleaner.com/ccleaner/version-history it says in part: I'm hoping we'll have a new CCleaner Portable that's built correctly by the time that CCleaner v6.03 is released next month. ----------------- 64-bit Win 10 Pro v21H2 build 19044.1826 * Firefox v102.0.1 * Microsoft Defender v4.18.2205.7-1.1.19400.3 * Malwarebytes Premium v4.5.11.202-1.0.1716 * 7-Zip v22.01 * CCleaner Free Portable v5.91.9537 Dell Inspiron 15 5584, Intel i5-8265U CPU, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G NVMe SSD, Intel UHD Graphics 620

Hi LeshaRB: Please see my 21-Jun-2022 post <above> which states in part: I download the ccsetup602.zip file and previewed the contents using 7-Zip, and it has the same incorrect folder structure (e.g., the CCleaner.exe and CCleaner64.exe executables are not located in the "root" with portable.dat - see image below), so I would advise against using it. If you unzip ccsetup602.zip and use it in its current condition it will incorrectly create scheduled tasks and dozens of registry entries like the ones shown in my 04-Jun-2022 post in mogli's 5.92 portable broken [download 5.91 from website]. ----------------- 64-bit Win 10 Pro v21H2 build 19044.1826 * Firefox v102.0.1 * Microsoft Defender v4.18.2205.7-1.1.19400.3 * Malwarebytes Premium v4.5.11.202-1.0.1716 * 7-Zip v22.01 * CCleaner Free Portable v5.91.9537 Dell Inspiron 15 5584, Intel i5-8265U CPU, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G NVMe SSD, Intel UHD Graphics 620

Hi arejfour: I can confirm that one of my recent MS Edge updates (likely v103.0.1264.62, rel. 14-Jul-2022) automatically turned on my Startup Boost setting at Settings | System and Performance | System. I couldn't figure out why my CCleaner custom clean scan kept reporting today that MS Edge was still running until I opened Task Manager and saw there were multiple instances of msedge.exe running in the background even though I hadn't opened that browser for a few days. As Nergal suggested in CC Cleaner tells me edge is Running but it isn't, make sure "Startup Boost" and "Continue Running Background Extensions and Apps When Microsoft Edge is Closed" are both turned OFF to ensure MS Edge processes don't continuously run in the background. ----------- 64-bit Win 10 Pro v21H2 build 19044.1766 * Firefox v102.0.1 (default browser) * MS Edge 103.0.1264.62 * Microsoft Defender v4.18.2205.7-1.1.19400.3 * Malwarebytes Premium v4.5.11.202-1.0.1716 * Macrium Reflect Free v8.0.6867 * CCleaner Free Portable v5.91.9537 * Inspiron 5583/5584 BIOS v1.18.0 Dell Inspiron 15 5584, Intel i5-8265U CPU, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G NVMe SSD, Intel UHD Graphics 620

Hi loustalou1: This won't help you now, but for future reference there are instructions for restoring registry backups created by CCleaner at How Can I Restore Registry Backups?. The following warning is posted in the CCleaner support article Clean the Windows Registry: There have been several posts in this CCleaner forum where the CCleaner registry cleaner damaged software, so as a general rule I only use this registry cleaner if I have uninstalled a program and need to remove orphaned files or registry entries that are causing a problem (e.g., interfering with re-installation of the program or causing a conflict with installation of another program). The Microsoft support article Microsoft Support Policy for the Use of Registry Cleaning Utilities also warns that: I own a Dell computer, and I normally use Revo Uninstaller Free in "Aggressive" mode to uninstall Dell utilities like SupportAssist, Dell Update, etc. to try and clean up orphaned files and registry entries often left behind by the uninstaller. Also note that there are dozens of recent threads in the Dell SupportAssist for PCs board about issues updating or re-installing the SupportAssist utility. For many users these problems are related to a major change in the system requirements for the latest SupportAssist v3.11.4.29 (released 23-Jun-2022) which now requires the .NET (Core) Runtime v5.0 in addition to the "classic" MS .NET Framework v4.7.2. See my 24-Jun-2022 post in DavG94's Dell SupportAssist Fails to Install for further details. EDIT: You also asked "why was I unable to restore the deleted dlls". Note that a .DLL (Dynamic Link Library) is a file that often contains code and data that can be used by more than one program. It is not a registry entry, and the registry cleaner in CCleaner will not actually remove a .DLL file from your hard drive. However, the registry cleaner might remove an important registry key that references (points to) that .DLL file. --------------- 64-bit Win 10 Pro v21H2 build 19044.1766 * Firefox v101.0.1 * Microsoft Defender v4.18.2205.7-1.1.19300.2 * Malwarebytes Premium v4.5.10.200-1.0.1702 * Macrium Reflect Free v8.0.6758 * Dell SupportAssist v3.11.4.29 * Dell Update for Windows Universal v4.5.0 * Inspiron 5583/5584 BIOS v1.18.0 * CCleaner Free Portable v5.91.9537 * Revo Uninstaller Free Portable v2.3.9 Dell Inspiron 15 5584, Intel i5-8265U CPU, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G NVMe SSD, Intel UHD Graphics 620

Hi Wolfzz: I just received an email from MajorGeeks informing me that they have pulled CCleaner Portable v6.01 from their servers and replaced it with CCleaner Portable v5.91. I checked at https://www.majorgeeks.com/files/details/ccleaner_portable.html and confirmed that their download links are currently offering ccsetup591.zip. ----------- 64-bit Win 10 Pro v21H2 build 19044.1766 * Firefox v101.0.1 * Microsoft Defender v4.18.2203.5-1.1.19200.6 * Malwarebytes Premium v4.5.10.200-1.0.1702 * CCleaner Free Portable v5.91.9537 Dell Inspiron 15 5584, Intel i5-8265U CPU, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G NVMe SSD, Intel UHD Graphics 620

Hi Wolfzz: Actually, there is a portable ccsetup601.zip file on the Piriform download server (https:// download.ccleaner.com/...) if you know where to look for it, but it is not posted on the builds page https://www.ccleaner.com/ccleaner/builds because of the problems it will create if you run the executables in their current state. I don't know why Piriform hasn't removed this .zip file from their download server. I downloaded the ccsetup601.zip file from MajorGeeks and previewed it in 7-Zip, and it has the same buggy folder structure as the ccsetup592.zip file that was recently pulled from the builds page (e.g., where the CCleaner64.exe is located in the \64x subfolder instead of the "root" folder where it should be with portable.dat). If you execute the CCleaner.exe or CCleaner64.exe executables from their current locations (i.e., without copying and pasting the executables into the "root" folder with portable.dat) you're going to create all sorts of problems. See mogli's bug report at 5.92 portable broken [download 5.91 from website] about issues switching to a non-English interface plus all the unwanted garbage (e.g., a CCleaner Update task in Task Scheduler and dozens of registry entries) that will be added to your system. Andavari noted <here> on 06-Jun-2022 in mogli's thread that "Where you unzipped CCleaner Portable make sure the portable.dat file is in the same folder as CCleaner.exe and CCleaner64.exe, it's required so it knows to not create registry data." I wasted a ridiculous amount of time yesterday cleaning up most of the garbage that CCleaner Portable v5.92 added to my Task Scheduler and registry before I rolled back to v5.91. I'll contact MajorGeeks and suggest they pull that portable ccsetup601.zip file from their servers. ----------- 64-bit Win 10 Pro v21H2 build 19044.1766 * Firefox v101.0.1 * Microsoft Defender v4.18.2203.5-1.1.19200.6 * Malwarebytes Premium v4.5.10.200-1.0.1702 * CCleaner Free Portable v5.91.9537 Dell Inspiron 15 5584, Intel i5-8265U CPU, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G NVMe SSD, Intel UHD Graphics 620

Hi Dave CCleaner: Apologies for going off topic, but in October 2019 you posted in Alex_Recuva's Download Link For the Portable Version is Downloading the Setup Version that download links for the portable builds of Speccy, Defraggler and Recuva would be "reestablished shortly" on their respective builds pages (e.g., at https://www.ccleaner.com/speccy/builds for Speccy) but those download links are still missing. Also see ZloboMiR's February 2020 No SSD NVM Info, which shows that the current Speccy v1.32.774 (not updated since 20-May-2018) is unable to display the S.M.A.R.T. status of most modern SSD drives. See my December 2021 post # 2409451 in Ben Meyer's Hard Drives – Still Pretty S.M.A.R.T. in the AskWoody forum where I compared Speccy to three other free hardware diagnostic utilities (note that some attached images are only viewable if you log in to that AskWoody forum). It certainly appears to me that Avast / Piriform has abandoned further development of Speccy, and I also fear that CCleaner Portable is heading for a similar demise now that the "standard" CCleaner.exe and CCleaner64.exe executables for the CCleaner user interface are being packaged with Performance Monitor, Software Updater, and all the other unnecessary features that don't really belong in a portable disk cleaner. ----------- 64-bit Win 10 Pro v21H2 build 19044.1766 * Firefox v101.0.1 * Microsoft Defender v4.18.2203.5-1.1.19200.6 * Malwarebytes Premium v4.5.10.200-1.0.1702 * CCleaner Free Portable v5.92.9652 Dell Inspiron 15 5584, Intel i5-8265U CPU, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G NVMe SSD, Intel UHD Graphics 620

Hi Peaform: Dave CCleaner's 20-Jun-2022 announcement <above> states that "As such, for the time being we have rolled back the portable version on the website to 5.91 until we can come up with a satisfactory solution ". There were bigger problems with CCleaner Portable v5.92 than the problem with non-English languages that mogli reported in 5.92 portable broken. See my 04-Jun-2022 post in bgavin's Bug Report: Portable 6.0.0.9727 for Windows about all the unexpected registry entries and Task Scheduler tasks that were created on my system by this buggy v5.92 release. According to Andavari's 06-Jun-2022 post <here> in bgavin's thread the registry entries were created because the portable.dat file was not located in the same folder as CCleaner.exe and CCleaner64.exe executables in CCleaner Portable v5.92. I now have to manually remove all these unnecessary registry keys and tasks from my system and will be going back to using CCleaner Portable v5.91 for now. I agree with your comment about Performance Optimizer, Software Updater, etc. I only use the Custom Clean feature and I suspect that most CCleaner Portable users would actually prefer to have many of the "extra" features like Performance Optimizer, etc, removed from the portable build. ----------- 64-bit Win 10 Pro v21H2 build 19044.1766 * Firefox v101.0.1 * Microsoft Defender v4.18.2203.5-1.1.19200.6 * Malwarebytes Premium v4.5.10.200-1.0.1702 * CCleaner Free Portable v5.92.9652 Dell Inspiron 15 5584, Intel i5-8265U CPU, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G NVMe SSD, Intel UHD Graphics 620

Hi Steve1209: I'm not sure I follow. I know I can configure my Firefox browser to clean my browsing history on exit with two settings - namely Privacy & Security | Browser Privacy | Cookies and Site Data | Delete Cookies and Site Data When Firefox is Closed as well as Privacy & Security | Browser Privacy | History | Use Custom Settings for History | Clear History When Firefox Closes | Settings.... Are you saying that having background updating enabled at General | Firefox Updates | Allow Firefox to | Automatically Install Update | When Firefox is Not Running so that Firefox updates in the background (i.e., even when Firefox.exe is not running and the browser is closed) can also trigger Firefox to clean items like your browsing and download history, cookies, cache, etc? You said in your original post that "CCleaner keeps reporting it's cleaning" your Firefox browser. If this happens again would you be able to capture a screenshot of the pop-up? There are all sorts of programs besides CCleaner that can clean your Firefox history. For example, I believe Norton 360 and other Norton antivirus programs (which I no longer use) have a scheduled background task at Settings | Administrative Settings | Firefox Cleanup that will automatically clean your Firefox history. ----------- 64-bit Win 10 Pro v21H2 build 19044.1706 * Firefox v101.0.0 * Microsoft Defender v4.18.2203.5-1.1.19200.5 * Malwarebytes Premium v4.5.9.198-1.0.1689 * CCleaner Free Portable v5.92.9652 Dell Inspiron 15 5584, Intel i5-8265U CPU, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G NVMe SSD, Intel UHD Graphics 620

Hi Steve1209: I don't want CCleaner cleaning anything in my Firefox browser but I noticed that the "Bookmarks" option was automatically enabled for Firefox (and other Firefox forks like Pale Moon, Waterfox, etc.) after I updated to CCleaner Portable v5.92 - see image below. I haven't updated to Firefox v6.00 yet to see if additional Firefox cleaning has been added, but the release notes at https://www.ccleaner.com/ccleaner/version-history for v5.92 state in part that "We added cleaning of bookmark backups in Edge and Firefox". I only use the Custom Clean function of CCleaner and I was able to disabled this bookmark cleaning at Custom Clean | Applications tab | Firefox before it did any damage, but if you use the Health Check function I suspect that cleaning of Firefox (or other Firefox forks like Pale Moon, Waterfox, etc.) is included there as well. If you use Health Check see the support article I’m Using Health Check.

Hi Andavari: My image below shows the three other files [ccleaner.ini, portable.dat and License.txt (optional)] I normally keep in the same folder as my CCleaner64.exe executable. I do not have a system with a 32-bit OS so I don't need the CCleaner.exe executable, and I use the English interface so I do not need the \lang subfolder in that same location. Note that I only use the Custom Clean feature and don't want to use Health Check, Software Updater, Performance Optimizer, or any of the other bloat that's been added to recent versions of CCleaner. As bgavin pointed out, unlike CCleaner Free Portable v5.91 and earlier versions, the unzipped ccsetup592.zip file no longer has the CCleaner64.exe and CCleaner.exe executables in the same "root" folder as portable.dat and License.txt. Anyone using CCleaner Portable v5.92 who made the made the mistake of running the CCleaner64.exe file while it was still located inside the \x64 subfolder (which I did while running a test for mogli) now has all this garbage in their registry. That's likely how I got the unwanted CCleaner Update task created in my Task Scheduler (shown in my first image <above>) as well. Piriform / Avast really messed things up in v5.92 when they moved the executables out of the "root" directory where portable.dat and License.txt are still located , and this needs to be fixed before the next portable version is posted at https://www.ccleaner.com/ccleaner/builds. ----------- 64-bit Win 10 Pro v21H2 build 19044.1706 * Firefox v101.0.0 * Microsoft Defender v4.18.2203.5-1.1.19200.5 * Malwarebytes Premium v4.5.9.198-1.0.1689 * CCleaner Free Portable v5.92.9652 Dell Inspiron 15 5584, Intel i5-8265U CPU, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G NVMe SSD, Intel UHD Graphics 620

Hi Dave CCleaner: I've never had the v6.00 update pushed out to my CCleaner Free Portable v5.92 (unzipped on 13-Apr-2022 before CCleaner v6.00 was released on 12-May-2022) that I run from a removable USB thumb drive. The ccleaner.ini file I'm using now was copied and pasted from my previous v5.91 portable and currently has: UpdateBackground=0 UpdateCheck=0 Note that I was running a test for another user (see my 13-Apr-2022 post in mogli's 5.92 Portable Broken) and made the mistake of unzipping a fresh copy of ccsetup592.zip on my hard drive in C:\Users\<myusername>\Downloads and immediately double-clicking the CCleaner64.exe file now located the \x64 subfolder, which generated a brand new ccleaner.ini file with all the default settings. As noted in mogli's thread, there is something seriously wrong with the structure of the folders and files in the ccsetp592.zip file and launching that CCleaner64.exe file appeared to create a scheduled CCleaner Update task in Task Scheduler that tries to run the emergency updater CCUpdate.exe, a file that normally isn't bundled with the Portable build. Note that I've deleted this scheduled CCleaner Update task since the image below was captured, as well as CCleanerDU.dll, CCleanerReactivator.dll and all the other unnecessary files and folders bundled inside ccsetup592.zip that aren't required to run the Portable version of CCleaner. I've never installed the "regular" version of CCleaner Free on my Win 10 computer but when I searched my registry today for "Piriform" I found dozens of registry entries in HKEY_CURRENT_USER\SOFTWARE\Piriform\CCleaner, HKEY_LOCAL_MACHINE\SOFTWARE\Piriform\CCleaner and others. I don't know when these registry entries were first created but I suspect most, if not all, were created when I launched CCIeaner64.exe during my 13-Apr-2022 test of CCleaner Free Portable v5.92 for mogli and created a new ccleaner.ini file (i.e., before I copied over my old v5.91 ccleaner.ini file with my customized settings and deleted all the other unnecessary files and folders bundled inside ccsetp592.zip that aren't required to run the Portable version of CCleaner). Portable software should never be allowed to make these types of changes to the registry. Here's just a partial list of what I found: ----------- 64-bit Win 10 Pro v21H2 build 19044.1706 * Firefox v101.0.0 * Microsoft Defender v4.18.2203.5-1.1.19200.5 * Malwarebytes Premium v4.5.9.198-1.0.1689 * CCleaner Free Portable v5.92.9652 Dell Inspiron 15 5584, Intel i5-8265U CPU, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G NVMe SSD, Intel UHD Graphics 620

Hi nima: Just an FYI that I was able to restore the non-English languages in CCleaner Free Portable v5.92 by moving the .exe executable (either CCleaner.exe from the \x86 subfolder and/or CCleaner64.exe from the \x64 subfolder) into the correct "root" folder where the portable.dat file and \lang subfolder are located. See the images in my 13-Apr-2022 post in mogli's bug report at 5.92 Portable Broken. If your .exe executables automatically upgraded from v5.92 to v6.00 after you unzipped the Portable ccsetup592.zip file (the version that is still available at https://www.ccleaner.com/ccleaner/builds as of 04-Jun-2022) then I suspect the same workaround would also allow you to switch to a non-English language in the v6.00 interface. ----------- 64-bit Win 10 Pro v21H2 build 19044.1706 * Firefox v101.0.0 * Microsoft Defender v4.18.2203.5-1.1.19200.5 * Malwarebytes Premium v4.5.9.198-1.0.1689 * Macrium Reflect Free v8.0.6758 * CCleaner Free Portable v5.92.9652 Dell Inspiron 15 5584, Intel i5-8265U CPU, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G NVMe SSD, Intel UHD Graphics 620

Hi bgavin: Just an aside, but note that you should be able to download older CCleaner Portable .zip files by browsing to https: // download.ccleaner.com/portable/ccsetupxxx.zip. For example, if you ever need the .zip file for CCleaner Portable v5.76 browse to https://download.ccleaner.com/portable/ccsetup576.zip .

Hi bgavin: See my thread How Do I Stop CCleaner Portable v5.76 From Automatically Checking for Updates? that I mentioned <above>, which includes images of the CCleaner Update task that was created in my Windows Task Scheduler when the Emergency Updater (CCUpdate.exe) was inadvertently added to my Portable build files. There is an explanation in my original 14-Jan-214 post about why this Emergency Updater was added to the "regular" CCleaner v5.36 installer in 2017, but it made no sense for this scheduled CCleaner Update task to be running in the background for my Portable build when the required CCUpdate.exe executable was located on a removable USB drive (D:\ drive) that was rarely plugged in to my computer. Here's an old image from my 2021 thread showing the scheduled CCleaner Update task repeatedly failing with an error (Last Run Result = 0x80070002) on my system because my USB thumb drive was unplugged and the task could not locate D:\Portable\CCleaner\CCUpdate.exe: I believe I simply right-clicked the Cleaner Update task in Task Scheduler and chose Delete from the pop-up context menu (see the TenForums tutorial How to Delete Scheduled Task in Windows 10) but I'm guessing I might still still have some stray registry left behind in my Windows registry. You could try running the registry cleaner in CCleaner to look for stray registry entries related to Piriform or CCleaner (or use regedit and search for registry entries related to "Piriform" as ALF60 suggested on 14-May-2022 in the Norton Tech Outpost thread CCleaner v6.0.9727 Released 12-May-2022, Portable Build Delayed), but I would suggestion caution if you choose to do so. I normally don't allow my CCleaner Portable build to make any connection to the backend Piriform / Avast servers (see my 21-Jan-2021 post in How Do I Stop CCleaner Portable v5.76 From Automatically Checking for Updates? about how I've created an outbound block in my Windows Firewall rules for CCleaner64.exe) but if you want to leave the CCleaner Portable settings at Options | Updates | Keep CCleaner Updated Automatically ENABLED or use any other feature in the CCleaner Portable interface that requires a connection to the backend Piriform / Avast servers then you might break that functionality. The main crux of the problem is that Piriform / Avast's idea of a Portable build is to just take the identical 32-bit CCleaner.exe and 64-bit CCleaner64.exe files used with the "regular" installed version of CCleaner, bundle them in a ccsetupxxx.zip file with some language files and a portable.dat file to make it a portable build, and ensure that any configuration changes made in the interface are saved in a ccleaner.ini file. What they really need to do is re-design CCleaner.exe and CCleaner64.exe files specifically for the portable build so that it can't create a scheduled Emergency Updater task or registry entries and doesn't include other unnecessary features like a Software Updater and Performance Optimizer that really don't belong in a portable program that can be run from a removable USB drive on multiple machines with different operating systems and different software/hardware configurations. I'm not sure what your script does, but the ccleaner.ini files will contain all the custom settings from your previous CCleaner Portable version. As long as your script only overwrites the old 32-bit CCleaner.exe (if required), 64-bit CCleaner64.exe and portable.dat files (plus any required language files if you use a non-English interface) and does not delete the old ccleaner.ini file or copy over any extraneous files like CCupdate.exe then there shouldn't be any need for your script to re-create the custom settings for your updated interface or perform other cleanup routines. I personally prefer to always keep my CCleaner Portable files in the same folder (in my case, in a folder I created on my removable thumb drive at D:\Portable\CCleaner) so that the path to my CCleaner64.exe file never changes and I won't need to create a new ccleaner.ini file with all the default configuration settings the first time I launch the updated CCleaner64.exe executable that I manually copied and pasted into that folder. ------------- 64-bit Win 10 Pro v21H2 build 19044.1706 * Firefox v100.0.2 * Microsoft Defender v4.18.2203.5-1.1.19200.5 * Malwarebytes Premium v4.5.9.198-1.0.1676 * Macrium Reflect Free v8.0.6758 * CCleaner Free Portable v5.92.9652 Dell Inspiron 15 5584, Intel i5-8265U CPU, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G NVMe SSD, Intel UHD Graphics 620

Hi bgavin: The change in folder structure (i.e, where the 32-bit CCleaner.exe and 64-bit CCleaner64.exe excutables were moved out of the root folder and into separate \x86 and \x64 subfolders) started with CCleaner Portable v5.92 - see mogli's 11-Ap-2022 5.92 Portable Broken about problems this created for non-English users. I suspect this is one of the issues that Piriform / Avast will have to fix before CCleaner Portable v6.0.x is ready for wide release. ------------- 64-bit Win 10 Pro v21H2 build 19044.1706 * Firefox v100.0.2 * Microsoft Defender v4.18.2203.5-1.1.19200.5 * Malwarebytes Premium v4.5.9.198-1.0.1676 * Macrium Reflect Free v8.0.6758 * CCleaner Free Portable v5.92.9652 Dell Inspiron 15 5584, Intel i5-8265U CPU, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G NVMe SSD, Intel UHD Graphics 620

Hi bgavin: Sorry, I realize my previous post might not have been clear. If I click "Check for Updates" in the CCleaner Free Portable interface and choose "Update Now" it doesn't actually install the "regular" CCleaner Free program on my hard drive. It just dumps files normally bundled inside the ccsetupxxx.exe installer (e.g., the Emergency Updater file CCUpdate.exe which is not normally included with the Portable version) on the removable USB thumb drive where my CCleaner Free Portable files are located. I'm sure I could update my CCleaner Free Portable v5.92.9652 to v6.00.9727 by downloading the "regular" ccsetup600.exe installer from https://www.ccleaner.com/ccleaner/builds, unpacking that self-extracting installer with 7-Zip and then copying the newer CCleaner64.exe v6.00.9727 executable to my removable USB thumb drive to replace the old CCleaner64.exe v5.92.9652 executable. However, I have no interest in using the new Performance Optimizer introduced in v6.00.9727 and prefer to wait until the developers at Piriform / Avast feel that they have CCleaner Portable v6.0.x version that is functioning correctly and ready for wide release, per employee Dave CCleaner's 18-May-2022 post <here>. ------------- 64-bit Win 10 Pro v21H2 build 19044.1706 * Firefox v100.0.2 * Microsoft Defender v4.18.2203.5-1.1.19200.5 * Malwarebytes Premium v4.5.9.198-1.0.1676 * Macrium Reflect Free v8.0.6758 * CCleaner Free Portable v5.92.9652 Dell Inspiron 15 5584, Intel i5-8265U CPU, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G NVMe SSD, Intel UHD Graphics 620

Hi bgavin: Are you sure your automatic update didn't inadvertently run the installer for the "regular" version of CCleaner (e.g., ccsetup600.exe)? I use CCleaner Free Portable v5.92.9652, and automatic updates are disabled at Options | Updates | Keep CCleaner Updated Automatically. If I click the "Check for Updates" link in the bottom right corner of the interface it currently detects that a newer v6.00.9727 of CCleaner64.exe is available, but I know from past experience that if I click "Update Now" it will download unwanted files from the "regular" version of CCleaner that are not normally bundled with the ccsetupxx.zip file. See nukecad's 14-Jan-2021 post in my thread How Do I Stop CCleaner Portable v5.76 From Automatically Checking for Updates?. I've learned the hard way never to allow CCleaner Free Portable to update itself. Instead I always unzip the latest ccsetupxxx.zip file from https://www.ccleaner.com/ccleaner/builds and then copy and paste the CCleaner64.exe and portable.dat files into the folder where I normally launch CCleaner Free Portable (currently a folder named D:\CCleaner on a removable USB thumb drive) to overwrite the old .exe and .dat files. I use the default English interface and only keep four files in that D:\CCleaner folder. ------------- 64-bit Win 10 Pro v21H2 build 19044.1706 * Firefox v100.0.2 * Microsoft Defender v4.18.2203.5-1.1.19200.5 * Malwarebytes Premium v4.5.9.198-1.0.1676 * Macrium Reflect Free v8.0.6758 * CCleaner Free Portable v5.92.9652 Dell Inspiron 15 5584, Intel i5-8265U CPU, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G NVMe SSD, Intel UHD Graphics 620
