To consolidate the files try running a 'Defrag Freespace' or 'Defrag Freespace (allow fragmentation)' from Actions>Advanced, it may take a while to complete on a 1TB drive. This explains the difference between the two options: https://www.ccleaner.com/docs/defraggler/using-defraggler/defragmenting-free-space-on-a-drive

I've done some testing and cannot replicate this UAC problem, so another couple of questions: Do you have Windows Fast Startup enabled? Are you using a Windows admin account or a standard user account?

I'll try some testing now that I have 20H2 installed. Are you using 'Run CCleaner when the computer starts' or 'Smart Cleaning', or both?

That can/will happen if Wipe Free Space (or Drive Wiper) is inturrupted unexpectedly, such as by a power failure or unplugging an external drive while it is wiping. Drive wipes work by filling up the 'free' parts of the disc with one or more files containing random data, (typically X's and Zeros) and then deleting that data. That way any files that you have previously deleted get overwritten with random data, and so cannot later be recovered by recovery software. Of course if anything should stop the drive wipe before it has deleted the random data that it has written then that random data will remain, taking up space on the disc. Normally if that happens then you have to find and delete those temporary files manually. However in your case it looks like you cancelled the wipe operation rather than there being an unexpected interruption. So the temporary files would get deleted, (which is why WinDirStat couldn't find them), but it seems that for some reason Windows itself didn't recognise that and thought they were still there - it just took giving Windows a poke (restart) to recognise that they had gone.

The offer as shown in that screenshot does not exist in that form since October of last year. Did you download that image from an old website? Offers for CCleaner Browser, or any other Piriform/Avast product, are now shown on a seperate page with very clear Decline/Accept buttons. like this:

Hi Andres Lara, I'll give your question a bump to make sure it's seen by @MeganCCleaner

I'm seeing this: Installed on 28/05/2020? Nope it was a couple of hours ago. I'll have to look into the "Windows Feature Experience Pack" And just for clarity I'm not and never have been signed up to the insiders.

There is a switch for this in Options>Advanced - if ticked it only applies to CCleaner : Although I do note that you say it's only started happening for you with 20H2, which as a full release has only been out today , so something may have changed that needs looking at.

Question - Why is Microsoft using H1 & H2 and not U1 & U2? (I know H1/H2 are accounting terms for 'Half 1/Half 2' but why not 'Update 1/Update 2'). LOL, I'm going to have to put U2 on the pub jukebox now.

Not really unless you ran CCleaner in Debug mode, and even then it won't tell you what was deleted just how long it took for each section. Fair enough if you are doing stuff like that there may be quite a lot of junk to clean and I'm not sure why the volume got reported wrongly. Like I say it may be something to do with that occasional double listing glitch which seem to be being difficult to track down, or maybe just not a priority? PS. Your choice of username (and your email address) has caused some discussion between the moderators here. We know where it originates - but it was very close to being banned as inappropriate for this forum. The Piriform staff may still take action, they trust us as moderators but it only take one person who has mod/admin permissions to decide otherwise and click the ban button. You might want to think about that in future.

Just done it here; also 10 mins whch seems lightning fast for a feature update. Interesting to see that they have gone with 20H2 for the version name, no doubt to avoid any possible confusion with the year 2010. I guess this is going to be the new 'official' naming convention from now and not just the before-release name.

40 GB would be a hell of a lot of junk; (the whole Windows 10 operating system isn't that big - some hard drives aren't that big). 40 MB would be more usual if you hadn't run CCleaner for a while, or if it was the first time you ran CCleaner. Can you tell us exactly what you did? (Step by step). ie. Did you run Health Check or Custom Clean? Did you run anything else? Which CCleaner version do you have? Which Windows version are you using? There is a known bug where occasionally CCleaner will list items twice, so I suspect that if it did actually show 40 GB it may have been a related false reading.

TBH you shouldn't really use a free/home version in a business enviroment. (The cost of business versions of software is usually tax deductable anyway). But everyone knows it happens and if it's not blatant then a blind eye will usually be turned. But it can mean that problems can be different from what a home user sees, and we tend to assume a home user unless the post says otherwise.

It was just a suggestion, I can't see your business network from here. Have you tried the Buisness Edition? As I am not an employee/staff member I'll leave it with @johnccleaner

Yes, it's odd that the redirect was working OK for me yesterday in both Firefox and Edge Chrome, but today (Sunday) both say again that the certificate is still out of date? TBH most should have updated their bookmarks to the new address by now, and it should only be a problem for old 3rd party webpages that may still have links to the old one.

The certificate for the old address was renewed yesterday, see the link that Hazelnut gives above.

As a business you should really be using the Speccy Business Edition on those machines rather than the free version. https://www.ccleaner.com/business/speccy-business-edition However the fact that there is "no internet connection" on "most of these workstations" may also be telling here. Publishing from Speccy sends a file to the Piriform servers, so needs an internet connection. I'm not sure if that needs to be a direct internet connection on the machine or if an endpoint can publish through a network? I would have thought that anything that needs to be network related is the reason why a Business Edition exists? Maybe @johnccleaner could clarify that point?

It's what is called an arms race. "We use advanced tools to wipe your drive". "We can get round that". The national security services usually have the best recovery tools. From reselling work computers if you take the hard drive out and whack it with a lump hammer that (usually) makes it unrecoverable.

The certificate has been renewed and the block is no longer happening. I'll mark this as solved and close the thread.

@Famppink That's simply a copy of the zdnet article that I posted six months ago.

The old forum web address (forum.piriform.com) was changed some time ago (to community.ccleaner.com), and so any old bookmarks/favourites that were pointing to the old address were being redirected to the new one. I've just done a quick test and if you try to use the old address then Firefox will now throw a block as you describe rather than redirecting. (So will Edge Chromium, and other browsers). I suspect that the SSL for the old address may have expired. I'll point it out to the staff. EDIT I've just checked and the SSL for the old address did indeed expire on 12th October, it just needs to be renewed. As you have found creating a new bookmark (or editing your existing bookmark) with the new forum address is the thing to do if you are having problems with the redirect.

The screens that you show are for updates to CCleaner itself, not other applications. I assume that you are using Health Check, which automatically checks for updates to certain applications. There are two ways to stop CCleaner updating other software. 1- Use Custom Clean instead of Health Check, Custom Clean does not automatically check for updates to other software. (There is a seperate 'Software Updater' in the tools section). You can set Custom Clean to be the default cleaning method in Options>Settings>CCleaner Home Screen. 2- If you still want to use Health Check then: After Health Check had done it's analysis then if it's found apps to update it will say so in the 'Security' button at the bottom, If it has found some to update then click on that button and in the screen that comes up untick the app(s) that you don't want to be updated. (Sorry can't show it fully as I don't have any to update). Then click 'Back To Overview' and continue with 'Make it Better'. NOTE - You will have to do that every time that you run Health Check, it doesn't remember what you unticked last time. (Which is another reason to use Custom Clean as default, that does remember your settings).

There is also a bigger delay in the first one at: [20:46:37] CUninstallOutlineDataSource:objectValueForTableColumn return : (null) [21:14:52] CSafariCleaner:GetCookies enter I'll flag the logs up to the staff to have the devs look at them.

That sounds like it has cleaned the junk, and is then bailing out when trying to access the Piriform servers to check 'Speed' & 'Security' which are the next 2 steps of the Health Check. There does seem to have been a problem with the servers earlier today which has now been fixed, try Health Check again and post back if it is still not working properly for you.
