Thanks for testing that and fidning that it was the 'History' checkmark for IE causing it. I'll try to remember that in case someone else reports they are seeing a similar error. I doubt that there are many people still using IE as a browser, but Windows and other apps do use it's temporary storage locations as a convinient dumping ground. (CCleaner itself uses IE's 'Temporary Internet Files' each time you launch CCleaner). I keep 'Temporary Internet Files' and 'Cookies' ticked for IE in Custom Clean, just to catch these temporary files from other apps. I'm not sure about Health Check, if you run that it may still clean IE's history and so trigger the event error for you?

Where did you download CCleaner from? Just want to make sure that it's genuine before continuing. SmartScreen will sometimes throw a block for a day or so after a new version of CCleaner is released until Windows Security Centre gets updated with the new signatures, etc. But CCleaner v5.76 has been out for a week and no one else has reported this problem. (Are you using a metered connection? If you have told Windows your connection is metered WSC definitions won't get updated). Try downloading the 'Slim' installer (3rd down) from here and install using that: https://www.piriform.com/ccleaner/builds If it's still being a problem try updating Windows. Or if you are sure that your CCleaner is genuine, eg. you've downloaded the Slim installer from the builds page, then simply ignore Smart Screen, close that warning, and carry on installing. (I've had to do that once before without any problems).

I assume that your CCleaner running OK? A bit of searching found this post in the Microsoft community asking about the same error, the same error code and process ID: https://answers.microsoft.com/en-us/windows/forum/windows_10-performance/event-10000-distributed-com/5644a2da-4166-4244-a288-6f7bc54dc9cf The answer is that it's a Windows error (so not a CCleaner bug, although running CCleaner seems to trigger it for you) - The advice from the Windows Tech expert is:

Well not sure just what happened to them, although as a library repair got them back it sounds as if they were actually still there but just not being shown by the OS. It was probably just an OS glitch on your machine rather that anything that CCleaner did, as I say no one else has reported photos going missing after running CCleaner on Big Sur. (Have you had a recent update to Big Sur? I see that there was a beta release of v11.2 on 13th Jan but I'm not sure if that has made it to general release yet). Good to hear that you got your photos back OK.

It is not a problem that needs fixing, that is in fact a common message to get when doing a file defragment. Mine actually says - "Some files were not defragmented", see the screenshot below. Most files have been defragmented but there are a few that couldn't be. If you look at the file list you will see that most of them now are in 1 piece, but there are a few that are still fragmented. Tip- Close the warning to scroll up and down the filelist to find what wasn't defragged. Or if you run another analyze it will just list which files are still fragmented; these are usually certain system files and/or Windows Defender logfiles, although I'm not sure just what they would be on an external drive. Usually they have not been defragged because they are protected files or because they had been used/changed since you anaylzed. PS. I'm assuming this is a hard drive connected by USB and not a USB Flash Drive/'Memory stick'? There is no need to defrag solid state media. (In fact Windows 10 own defragmenter will not let you do it).

@RogerOverwhich CCleaner version are you using? (And which Windows version/which AV?) This thread is seven months old and the original poster was using CC v5.66 which is an old version. The latest CCleaner is v5.76, a whole ten version later than this thread. There was an event log error being generated, but that has supposedly been fixed with newer CC versions. PS. WebCacheV01.dat stores information about which websites have been visited with IE/Edge (and some other stuff like windows searches). It can sometimes be left in a 'dirty shudown' state, which can cause issues.

As I say I'm not familiar with Mac but we haven't seen any similar report from other Big Sur users. PS. I like your typo in the first post above. (Big Slur). Are you sure that it was CCleaner that removed them? There have been reports elsewhere of photos going missing during the update to Big Sur. Have a look at these to see if you can recover them: https://www.cisdem.com/resource/lost-photos-after-macos-update.html https://www.fireebok.com/resource/three-ways-to-recover-lost-data-after-upgrading-macos-big-sur.html

I'm not familiar with MACs, but seeing as no one answered since you first asked on Friday: Where were the photos saved? If they were in a temporary directory, where the OS stores temporary files, then it's probably been cleaned out. If they were in the Photo Library then that could be another question.

There is no need to post the same question twice, I've merged then together so that any answers will be in the same place. (and it is the same question, even though one is Health Check and one is Custom Clean it will be the same files that you are seeing). When you have run a Custom Clean does it tell you the the browser files have been 'Skipped'? If so that's because the browser or some component of it is still open - CCleaner can not clear files that are open. Like this clean done when Firefox was open: If it's not showing 'Skipped' following a Custom Clean then what is it showing?, a screenshot might help. Things not seeming to be cleaned/removed can be a common missconception - some files will come back as soon as you have cleaned them. There various reasons why some files will come straight back, (with browser files it's usually syncing that does that), see this for a fuller explanation and how to stop some of that happening:

From what you say I assume that you already had all Smart Cleaning options turned off. (If not then turn them off). What you are seeing will be because the way that Automatic Updates work has changed so that CCleaner Free users can now get automatic updates. That puts an icon in your system tray, if you don't want to see it then you have to turn automatic updates off. Go to Options>Updates and untick 'Keep CCleaner updated Automatically'. The icon should then disappear.

Just for info while we are talking about RAM and Task Manager: Another memory 'oddity' in Task Manager that I've been asked about in the past is why the Committed memory total is, nearly always, higher that the actual RAM installed. That's because when Windows calculates the 'committed' memory some of it can be in RAM and some in the Pagefile. So Task Manager's 'Commited Memory' shows your RAM size plus your Pagefile size for the total memory available. It could even be higher if extra virtual memory (as well as the pagefile) has been allocated.

I think this notification issue may be because v5.75/ v5.76 are classed as 'Important Updates', and so are being notified in a different way from regular updates. Although the 'Important Update' notification facility has been available since 2018 this is the first time it has been used. Because it's an 'Important update', rather than just a regular product update, it can bypass your usual notification settings and show a notification anyway. You can read about the difference between 'Regular' updates and 'Important' updates in this article from 2018: (of course the screenshots there are out of date now). https://www.ccleaner.com/knowledge/introducing-new-and-improved-ccleaner-update-settings

Speccy only reports what Windows is telling it, and Windows doesn't always get it right. When it comes to RAM speed TM used to show the standard figure given by the manufacturer. If you overclocked the RAM then TM would still show that same base speed. It seems that Speccy is still reading that 'Base speed' variable from Windows, and so Speccy is still showing the standard speed for your RAM. As for the number of slots - I note that Task Manager is also showing that you have 2 slots used out of 4: "Izmantotie slots 2 no 4". So Windows thinks that you have 4 slots, and Speccy is simply reporting what Windows says.

As said above: PS. 'Win7UI.exe' is the Atheros Bluetooth System Tray icon and settings App, the registry entry is there just in case it is installed. The unused registry entry being there makes no difference to how your computer runs. If you remove it Windows will probably put it back later in an update. https://answers.microsoft.com/en-us/windows/forum/all/peculiar-finding-in-ccleaner/8fae2270-3050-48e3-92e0-00a79bf368cb

Updating to 5.76 would be the easiest way. Is there a particular reason why you are avoiding doing that?

Following Patch Tuesday I'm now on build 19042.746. I'd update Windows if it hasn't already and then see if CCleaner v5.76 will install for you. Download the 'Slim' installer "ccsetup576_slim.exe" from here and double click it to install: https://www.piriform.com/ccleaner/builds BTW. I assume that's a Local Group Policy and you are not running a business network? Business networks need a different edition of CCleaner: https://www.ccleaner.com/business/ccleaner-network-edition

As Nergal says these are not 'tracking' you as such, Health Check calls all browser/internet related temporary files 'trackers'. As you say that you are getting a lot at startup I suspect that you have browser syncing (and pre-loading?) turned on. Or possibly 'Live tiles' on the Start menu for news, weather, etc. For a fuller explanation, and to work out what they are and where they come from have a look at this post:

I think that we all agree that this shouldn't be happening with the portable.

Yes, CCupdate.exe is the emergency updater, and creates that task to check for emergency updates. (You can delete them). But it's not in the Portable version that I have downloaded here: It looks that what has happened is that by using the updater you have installed regular CCleaner onto your USB stick. I believe that is what the update would do; I think that as far as the updater is concerned you just have regular CCleaner Free installed at a non-standard location (the USB stick) and so it will install the new version there. There again, as far as I am aware Portable would always do that if you updated from within CCleaner Portable itself. It could be a bigger problem now if you left Automatic Updated ticked in the portable so that it did it itself rather than just prompting you. To avoid that happening in future ignore the update prompt and download the new Portable from the Builds page as you would previously have done. Make sure you turn off Automatic Updating in the new Portable version. @Dave CCleaner any comment about this?

Just for interest I did a Custom Clean analyze of Internet Explorer Temporary internet Files. (Of course I haven't been using IE or any app that I know uses IE storage locations). It found the following 8 entries to clean: Checking the individual files all 8 were put there by CCleaner itself. Usually with CCleaner Pro I only see 2 of them, if I bother to look: But on this occasion I had also just run the Portable Free version of CCleaner which is where the other 6 came from, because I hadn't bothered to turn off data sharing or automatic updates in the Portable. The files themselves contain information about the CC version number, settings configuration, whether its the Free or the Pro or a trial, etc. So everytime that you open CCleaner it is putting at least a couple of files in IE's temporary storage locations, (more if you've opted to share usage data, automatic updates, etc.), and then deleting them again when you actualy run CCleaner. Other apps do the same, but don't clean up after themselves like CCleaner does.

That is an unusual one, 0x6 is a Windows 'Invalid Handle' error. Which Windows version are you using? I suggest that as a first try you restart your computer, make sure that CCleaner is not running in the background (if it is then 'end task' in Task Manager), and then use the 'Slim' installer (3rd down in this link) to try installing v5.76 again: https://www.piriform.com/ccleaner/builds

They are specifically mentioned in the v5.76 release notes: https://www.ccleaner.com/knowledge/ccleaner-v5768269

You can't fully uninstall Edge/IE, they are integrated into Windows and Windows will not work properly without them. Even something as basic as the search on File Explorer uses Bing (via Edge) these days. As I said above may other apps use IE's storage space for temporary files, even though these are not generated by IE because they are in IEs temporary storage locations CCleaner sees them as belonging to IE, Other apps such as Skype, Windows Media Player, Live Tiles on the start menu, etc., etc.use Edge/IE storage locations when they need to store temporary files. It's just somewhere convienient to put them. Again you can see that by using Custom Clean to analyze Internet explorer- there will always be files in Internet Explorer Temporary Internet Files, files that haven't come from IE. (At least one of them comes from CCleaner itself everytime you open it). It's a bit chilly up here in Cumbria at the moment with snow on the fells but we're not supposed to be leaving the house anyway; and somebody shut all the pubs so we have to drink our beer alone.

If you had read the changelog you would see that CCleaner Free is now able to give you automatic updating. (That option only used to be available for Pro users who had paid for their CCleaner). To enable this CCleaner now runs a background task to check for updates every 12 hours, which is what you are seeing. If you don't want that then simply turn off the automatic update option. Go to - Options>Updates - and untick 'Keep Ccleaner updated automatically'. If you are having problems turning that off then give a shout.

As far as I am aware Brave browser deletes it's cookies by default. Which suggest that the cookies, and temporary files that Health Check is finding are from somewhere else and not from Brave browser. Smart Cleaner browser cleaning is only looking to clean the Brave browser if that is what you have ticked in browser cleaning, (which has already cleaned itself anyway). Only the browser you have just closed, not those cookies, etc from elsewhere that Health Check is finding after the browser has been closed/cleaned. The extra stuff that Health Check is then finding is probably from Edge or Internet Explorer temporary storage. You may say that you never use those browsers, but Windows itself uses their storage, as do many Microsoft applications, even if you never open those browsers. Again, what Health Check is finding is not related to Brave, it's other stuff. You could check that by not running Health Check and instead opening Custom Clean. Right click in turn on each entry under Edge and Internet Explorer and select analyze to see what is found. There are always 'Temporary internet files' and often 'Cookies' found for IE, and usually something in Edge/Edge Chrome as well.
