That should be safe enough, it's one of the things that reg cleaners are meant to be used for. Again it's not really necessary, (but we all like a 'clean' computer). PS. With Windows 10 those leftovers should eventually get removed anyway, either at the monthly Patch Tuesday or more likely at the bi-anual Feature (version) Updates. Those are also the times when you'll most often see new system entries that the reg cleaner doesn't recognise, although other smaller updates can also change the registry. It's those regular changes that make it unwise to use a reg cleaner indiscriminately with Win 10.

We saw a few cases when automatic updates first became available for Free users where it took Windows Task Scheduler a while to sort the new background task out. (Opening both Smart Cleaning and Automatic Updates and then closing them in a particular order usually gave Windows the poke it needed). Yours seem to be working as it should now, if it starts playing up again give another shout.

That seems quick for Disk Clean-up to have run a system files clean up, especially just after a Patch Tuesday. Did you select Clean up system files? Were all the boxes ticked? And just in case it helps work things out, what is that filename at the top of the CCleaner results window when it's stuck? You could try using Health Check to see if that will clear it, but I suspect it will also get stuck. Be aware that Health Check Uses it's own rules and does not respect the ticks/unticks from Custom Clean. If you have not done a "Restart" (not a shutdown) for a while then that can often 'unstick' system files.

Odd, that shouldn't happen. You can see here that it's ticked but there is no icon in the system tray. But if I tick automatic updates instead then the icon appears: Does the icon come back for you if you tick the 'Notify' box (only) again?

The clean is getting stuck on 'System - Temporary Files'. (I can't make out the filename itself; looks like 'Amd%.ini' or something similar?) You could try unticking that category to see if CCleaner will finish then. But that isn't realy solving the problem, only bypassing it, so: Run the built in Windows 'Disk Clean-up' selecting 'Clean up system files' - It will take a while to complete, 30 minutes plus is not unusual. That should clear out whatever system file it is that CCleaner is getting stuck on. PS. It looks like you had CCleaner open (and stuck) while trying to uninstall it, that would stop it uninstalling until you closed it.

Are you using Custom Clean or Health Check? There can be different reasons for it sticking depending on which one you are using. If you can post a screenshot of it when it's stuck that would help us work out what may be the cause, and how you can fix it. It also usually helps to tell us what Windows version you have, what CCleaner version, and what antivirus.

The defaults in Custom Clean are simply the apps/items that most people would want to have cleaned, you can change them of course by ticking/unticking the categories. If you use Health Check instead of Custom Clean than that also has it's own set of defaults, mostly the same as Custom Cleans defaults but with a few more. You can tell it to leave something alone but you have to do that every time that you run Health Check. You cannot change what Health Check cleans by default. Just to refine the link that Hazelnut gave you, these describe the Custom Clean categories that you will see on the 'Windows' and 'Applications' tabs: https://www.ccleaner.com/docs/ccleaner/ccleaner-rules/windows-tab https://www.ccleaner.com/docs/ccleaner/ccleaner-rules/applications-tab If you want to see deeper into what files each of the Custom Clean categories is finding on your machine then: Right-Click on the category you want to look at. In the popup menu click 'Analyze ........'. In the results window click on anything found to see a list of files found to clean. (You can shortcut that by setting Options>Advanced>'Cleaning results level of detail' to 'File list'). Of course that will only show something if there is something there to be cleaned.

Do you mean "Skip User Account Control warning" in the CCelaner Advanced Options?

I've not seen Canadian rye whisky on sale round here for a number of years, it used to be in the local supermarket. (About 12 years since I last bought a bottle of it). It used to be about 3/4 the price of Scotch, Irish, or Bourbon - probably down to taxes. We now have a whisky distillery here in Cumbria, English Whisky is comparable to Scotch or Irish. https://www.lakesdistillery.com/whiskymakers-reserve-i4754

It's only been 5 days since they said they escalated it but, @Dave CCleaner could you check on this support ticket please? PS. Scotch Whisky (double distilled) doesn't have an 'e'. Whiskey with an 'e' is the Irish (triple distilled) , nothing wrong with Irish whiskey. Bourbon whiskey also uses an 'e'. (Irish migrant influence?) Japanese whisky could be spelt either way depending on who translated it from where.

Moved to CCleaner for Mac.

I've just registered on another forum and one of the verification questions was this: That's a bit surreal - Hang on while I ask an infinite number of monkeys.

Mozilla have now put a block on this bug so that it can't be triggered from Firefox: https://www.bleepingcomputer.com/news/software/mozilla-fixes-windows-10-ntfs-corruption-bug-in-firefox/ It can still be triggered from Windows itself, and from Chrome. It's Patch Tuesday later today so MS may fix it as part of that.

I understand now what is happening for you. This is a bug in CCleaner that is affecting some people but not everyone, it is know about and is being investigated. Smart Cleaning is cleaning the browser. But it is then closing the closing the background task for Smart Cleaning, which it shouldn't do and is why the icon disappears. Until it is fixed there is something that you can do. When you have closed the browser and the CCleaner icon disappears simply open and close CCleaner and Smart Cleaning will restart and the icon will come back. You don't need to do anything in CCleaner, just open and close it, - (but while it's open you could run a clean just to make sure that the browser has been cleaned).

When you install CCleaner it will give you the option to create a new desktop icon. If you have installed without adding a desktop icon then you can either: Reinstall CCleaner this time selecting the option. (There's no need to uninstall first). OR Open file explorer and browse to: C:\Program Files\CCleaner Right-click on CCleaner64.exe and in the menu that comes up hover your pointer over 'Send to' and then click on 'Desktop (create shortcut).

Interesting indeed, thanks for trying it. It's not something that I've played about with because I prefer to stay logged out of sites unless I'm actually using them. Especially sites like Amazon that have my debit card details. (I just see that as basic security, and it only takes seconds to log in again). I suppose it would need deeper digging to find out just what is inside each cookie, or some trial and error like you have done there. I'm not sure that CCleaner could come up with a 'recommended' list of cookies to keep for Firefox, there would just be too many variants,especially with this new partitioning.

I think that you are missunderstanding what the different settings do. 'Launch the CCleaner app window each time the computer starts' puts a flashing icon in the system tray when the computer starts, but ony for seconds while the clean is running and it disappears when the clean has finished. There are two functions that will keep an icon in the system tray (not flashing) these are: Smart Cleaning: If you have Smart Cleaning enabled it needs to run in the background to monitor for junk building up, or for a browser being closed. 'Keep CCleaner updated automatically': This needs to run in the background to periodically check if an update is avaiable. (I believe it checks every 12 hours). If either of those options is selected then you will get the icon in the system tray because it is running in the background . (If you manualy close it then those functions will stop working). If you just want a CCleaner icon on the taskbar so that you can launch CCleaner quickly then open file explorer and browse to: C:\Program Files\CCleaner Right-click on CCleaner64.exe, and in the menu that comes up click 'Pin to taskbar'.

The problem ther is that at 90% capacity used that disk is pretty full, - You have run out of free space required for a defragment to work. Even the built in Windows defragmenter wont work with a HDD drive that is that full. You may/will also start running into other probems with Windows not having the free disc space that it needs to work properly. The general recommendation is that you should have at least 15% free space for a defrag of a HDD to be sucessful. https://www.howtogeek.com/324956/how-much-free-space-should-you-leave-on-your-windows-pc/ Suggestions: I would try running Disk Clean-up with 'Clean up system files' selected to see if you can get that used space down any. (The 'Windows update clean up' files in particular can be very large). A lot of what is listed there seem to be 'Features-on-Demand' packages, are you actually using those features? If not you can remove them. https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/features-on-demand-v2--capabilities Are you using OneDrive? see this: https://www.lightroomqueen.com/community/threads/onedrive-how-it-gobbled-up-my-hard-drive.35708/ Do you need all the files on the disc? Delete any old files that you don't want/need anymore - and/or move some of the files onto another drive, memory stick, etc. In the end though if you want to keep those files on the computer itself you will have to get a bigger drive installed, (or a second internal or external drive).

As already said you shouldn't be using any registry cleaner except for troubleshooting/fixing specific problems. As already said the developers are already looking to remove it from the main menus in CCleaner, so that people are not tempted to use it when they shouldn't do. (We moderators been nagging them to do this for over a year now). It can be a useful tool if it is used correctly; so it probably won't be scrapped altogether. (Chainsaws are not the right tool for carving your Sunday roast, but are useful when used correctly for the right job)

Here's a bit of an odd one. Since November (lockdown) I've been tethering my laptop to my phones data via USB. Yesterday morning that was working as normal. HIbernated the laptop and went shopping, etc. Woke the laptop Yesterday afternoon and it would no longer see the phone as a router via USB. (The phone can still be seen, and used as a media device through the same connection). USB port checks OK, phone check OK, USB cable checks OK. I could only think that something has messed up the driver for tethering, but I hadn't updated or changed anything and the connection is metered so Windows shouldn't have done either. The only things that should bypass the metered connection setting is Defender, or MS critical updates. Looking at the update history there was indeed a defender update applied yesterday. I also notice that when opening Task Manager 'System Interrupts' are at 100% CPU for a number of seconds, often a sign of a driver problem. So I can only assume that the Defender update has 'broken' the driver for USB tethering. Probably just a temporary glitch so I'm not going to mess about with the drivers in Device Manager. It's not a great problem, I'm just using the phone as a mobile wifi hotspot instead.

That is a system entry relating to a system file and Windows is putting it back if you remove it, leave it alone. (It's part of the upcoming Spring 2021 update to Windows 10, it's just been put on most machines early in preparation for the update). In fact we reccomend that you leave all registry entries in Windows 10 alone. Our advice, and Microsoft's, is - don't use any registry cleaner with Windows 10 - if you do you may 'break' your Windows 10 and have to reinstall Windows from scratch. Windows 10 changes the registry frequently, and registry cleaning apps will never be able to keep up with that. You may get away with using one with no problems for months or years, but it's not worth the risk. Registry cleaning is an advanced tool (mainly for use on an already broken computer), it's not meant for regular use and will not speed up a working machine in any way. Here is the Microsoft article about (not) using regisrty cleaners: https://support.microsoft.com/en-gb/help/2563254/microsoft-support-policy-for-the-use-of-registry-cleaning-utilities Also see this post from Dave CCleaner about the Registry Cleaner in CCleaner: https://community.ccleaner.com/topic/59952-i-get-a-registry-error-on-ccleaner-on-windows-10-i-have-scanned-5-times/?tab=comments#comment-326804

I'd say that it is not something for CCleaner to 'sort out. It's just a case of us users getting used to the fact that Firefox is now saving more cookies (or multiple copies of the same cookies for different sites). Firefox has just made the cookies more specific, so that any partitioned cookies/supercookies that you 'keep' will now be kept for that particular site and not for any other site. Which makes sense from a security point of view. As long as you keep the cookie you want for the site you want then there is no real difference to what you have always done in the past. It's just that Firefox is storing more copies of cookies, with longer names specific to a certain website, so you have to look at more cookies to decide which is the one you want to keep and for which site. There is nothing that CCleaner can do about how many (copies of) cookies Firefox now stores. - Other than cleaning them when you tell it to of course. I would not be at all surprised if Chrome and other browsers start doing the same and partitioning cookies as soon as they can make the changes.

Are you using an Administrator account when uninstalling? Is the browser still running background processes? Try the suggestions here:

I'm not sure then, especially with Winapp2 in the mix. It does seem odd that CCleaner should delete some history but not all of it. That would suggest that the parts not being cleaned are somehow protected, or are being cleaned but being synced straight back? Another possibility is that the bookmarks are somehow being pre-loaded into the history when you launch Chrome? Is it all bookmarks that are showing in the history, or just the ones that you have visited in the last session? (I'm just thinking out loud, I won't have Chrome on my computer so can't try and check anything). Anyone else have any suggestions? PS. Yes you did start 2 threads with the same question, I thought it was unusual for a regular member. The first was 3 hours before this one and just said "Chrome download history is not being cleared. " I can put it back if you want?
