I'm wondering if it happens because there's deleted files in the Recycle Bin, and then a major Win10 upgrade takes place.

Wouldn't be the first publisher to do that kind of thing when they move onto doing a subscription only model where they want you to pay each and every year.

I've seen that mentioned online the past few days. As far as the "last version" I know a few people in businesses when they were doing the forced upgrades where Win10 really was their last version, some bought Macs and others started using Linux.

I'd recommend finding where your Chrome profile is stored, and then make a ZIP backup copy of it, doing so backs up all of your configuration. You'd then only have to remember to keep that ZIP backup up-to-date when you've made significant enough changes.

See if anything in the following topic helps (especially pay attention to using the portable version to update an old version if the installer version always fails): https://community.ccleaner.com/topic/5739-solution-when-ccleaner-wont-install-or-download-windows/

If deactivating the updates then in a short amount of time there will be an outdated vulnerable version on the system, and who knows if a newer version will be installed when doing the once or twice yearly large Windows Upgrade since Edge Chromium has it's own update separate from Windows Updates.

I removed your attachment. Re-Post in an image format or plain text.

I prefer the old original Edge but it's now dead. I don't like the update schedule for Edge Chromium, it's too rapid and we're more-or-less testing it for them. A more sane update schedule for it would be monthly via Windows Updates.

Possibly could be an issue, however some other tools that wipe free space will wipe by placing them into a temporary folder which I assume "might be safer" than just writing to the root of a disk drive. So maybe they could implement something like "C:\CCWFS_05292021_646PM" with the date an time to insure it doesn't end up in a folder that is pre-existing, then also delete that temporary folder upon completion even if the user cancels WFS.

You could try this on that PC where the OS is "bugged": https://community.ccleaner.com/topic/60460-ccleaner-does-not-empty-my-recycle-bin-even-is-checked/?tab=comments#comment-329104 Other than that a new fresh install of Windows will solve all the issues quickly, including getting rid of any potential malware which could be part of the cause.

CCleaner should be able to remove Drive Wiper/Wipe Free Space ("WFS") leftover ZZZ files/folders without having to do a potentially very time consuming re-run of WFS to full completion. CCleaner should be able to detect that the user cancelled WFS, and then just do a normal fast delete of the ZZZ files/folders it created so the user doesn't have reduced free disk space. A recent topic shows it's still an issue, and at this point for too many years: https://community.ccleaner.com/topic/60499-zzz-folders-zzz-files-and-thousands-of-zip-files/

For just seeing what the drive is capable of I'd recommend using CrystalDiskInfo (https://crystalmark.info/en/download) (it's free and only lists details about disk drives). In it look for: * Interface: Should state UASP (Serial ATA). UASP allows the drive to function faster when plugged into a USB 3.0 port, it allows up to 70% faster read speeds and 40% faster write speeds. If it's a desktop PC only plug the drive into the USB 3.0 ports on the back of the PC, it's a little know fact that those are typically always faster than any USB 3.0 ports on the front or top of a PC which may be using some add-on to add USB 3.0 ports to a more convenient yet slower location. If you're using Windows 10 and if the drive is slow it can mean that Write Cache is disabled. Windows 10 used to have Write Cache enabled by default, but now it's off by default. Off is safer, but much slower, and you have to 100% of the time safely remove the device to prevent corruption. * Transfer Mode: Should state SATA/300 | SATA/600 SATA/300 = 300 Gbps (often incorrectly called "SATA 2"). SATA/600 = 600 Gbps (often incorrectly called "SATA 3").

It is bizarre to instantly scan. I guess the only way to find out if it's still working is wait awhile, and then see if it eventually finds something to remove. One thing to try is right click the CCleaner icon and select to run it as administrator, only other thing I can think of is perhaps it's a privileges thing since it does need admin level to clean the registry.

Perhaps because the scan finds nothing that could be the reason? Or perhaps items are unchecked for it to scan, that's a possibility. On my Win10 system with an SSD and everything checked it finds nothing, although the scan takes 3 or 4 seconds.

That's the best advice in this now one year old topic. I think too many are hung up on WFS as perhaps a privacy aspect when in reality it's a tool best used when getting rid of a hard disk or PC.

Look on the Trend Micro website for an official removal tool. Most antivirus vendors supply one which will remove more left-overs on the disk drive and sometimes in the registry too. Although those removal tools don't necessarily remove all of the left-overs.

ChkDsk shows more information that you can digest, plus it can be more powerful such as running a surface scan using ChkDsk /R to find bad sectors which is something I do no more than once or twice per year on my backup hard disk but that takes hours on a 1TB or larger hard disk. The This PC method isn't really all that useful to be honest, it's just a quick way but it gives very little information.

Well known issue, see this search and preferably follow what a PC manufacturer or well known tech website states - it doesn't require any 3rd party software to fix it either, what's built into Windows will help you remedy the issue: https://duckduckgo.com/?q=Fix+100%+disk+usage+in+Windows+10 Edit: As for the built in Windows 10 Optimize Drives running in the background and interfering with your work on the PC you can get around that by manually running it such as; Start it when you know you won't be using the PC for many hours such as before you go to bed and let it run overnight (remember to turn off your monitor so it isn't needlessly using power and being worn out): 1. Open: This PC 2. Right click your hard disk drive and select: Properties 3. Click: Tools 4. Under Error Checking click: Check 5. Under Optimize and defragment drive click: Optimize, then in the Optimize Drives window highlight your hard disk drive and select Optimize. 6. You can now turn off your monitor and leave the computer to finish optimizing the drive without interruption. One thing is for certain with an SSD the optimization is done so quickly it won't interrupt you when working, you won't even notice it. Getting something like a small SSD OS boot drive of at least 240GB to 256GB is more-or-less a standard (although with current pricing at least 480GB to 512GB makes more sense price-wise) and is all that's really needed for Windows 10 to fit comfortably. The hard disk drive can be repurposed as a mass storage data drive to store music, movies, etc., that you don't want taking up the SSD capacity.

Could be something to do with some user profile corruption or some other corruption. The upgrade to Windows 10 v21H1 caused some corruption on my system drive. I repaired it running: 1. In Command Prompt or PowerShell run: ChkDsk /F C: 2. Restart the PC. 3. In Command Prompt or PowerShell run (will take several minutes to complete): DISM.exe /Online /Cleanup-image /Restorehealth 4. In Command Prompt or PowerShell run (will take several minutes to complete): SFC /scannow 5. Restart the PC.

They should honor exclusions regardless of the mode selected. I'd personally like the ability to completely hide things from view in the GUI I'll never use like Health Check, etc., that way it won't be accidentally clicked. Sort of a CCleaner classic!

Try right clicking the CCleaner icon and choose: Run as administrator See if that works. Sometimes when CCleaner can't clean something that "may work", but not always.

Most of what's listed under 'Advanced' can be left alone, especially things like Windows Event Logs I'd personally never clean since that can give a clue to what's wrong with a PC. One thing in 'Advanced' that helps is when you've manually configured CCleaner in 'Options > Include' to delete a particular file or contents of a folder (such as: C:\Temp, or a software that isn't already cleaned by CCleaner, etc.,). Then under 'Advanced' you'd have to enable/tick 'Custom Files and Folders' otherwise it wouldn't clean your manually configured Include. It's worth looking at the Docs site for more detailed info: https://www.ccleaner.com/docs

My thinking is (without actually trying it) is there's something with the OEM installation that is perhaps causing it, and a fresh install could possibly fix it - that's a big guess. One of these days I might actually get around to doing a clean install, but not today.

If you're using Custom Clean as detailed in the provided link above you can actually force CCleaner to never touch anything in your Firefox Profile. To do that you'd need to input an Exclude of the folder/path where your Firefox Profile resides.
