After upgrading Windows 10 to Windows 11, CCleaner still shows Windows 10 at the bottom left of the program box when I open it. How come and how do I remedy that?
Try reinstalling CCleaner to see if it picks up the change then.
Download an installer from here: Download CCleaner builds | CCleaner Portable, Slim, and more
Double click the downloaded installer to reinstall a fresh CCleaner.
Don’t uninstall the old one first - that way the new install will pick up your settings, licence key, etc from the old one.
If it still shows Win 10 then you could then try an uninstall/reinstall, renember to make a note of your settings and licence key because you will have to put them back yourself.
Just to check; this is a fully compatible machine for Win 11 and you haven’t used the workrounds to update an ‘unsupported hardware’ machine?

Yeah, machine fully Win 11 compatible. Used Windows 11 Installation Assistant. All other programs and such work fine. Same with hardware.
Already tried installing over current CCleaner installation. Will try a fresh removal/install when I get a chance. Thanks for the reply.
TBH I have previously updated a ‘non-supported’ machine to Win11 (it failed every one of the MS upgrade requirements) and the CCleaner Free on that did recognise it as Win 11.
However that was a fresh install of Win 11 (using Rufus to get round the MS requirements) , and it was also a fresh install of CCleaner Free.
One thing that would be interesting before you uninstall/reinstall CCleaner.
In the currrent CCleaner that says Win10 if you go to Software Updater and do a scan is it offering you updates for Win 10 or for Win 11?
I don’t advise ever letting CCleaner try to do the Windows Updates, Windows itself will do them if they are needed for your machine.
If you note here it is currently offering to do 2 optional ‘Preview’ updates, they are not needed and Windows itself will not do ‘Preview’ updates unless you click a button to let it. Windows will do the ‘Full release’ version of them (next Tuesday).
(PS. I have seen CCleaners Software Updater offer Windows Updates to a machine where that particular update was being blocked by Windows itself because it was not compatible with that particular make of machine yet).

Sorry about taking so long to reply. I work a lot. 60+ hours a week.
Anyhow, good call on the Updater. it is offering Previews for Windows 11. No, I never install the Preview updates. I also only download them through Windows Update. So… I’m guessing that CCleaner still shows Windows 10 on the interface but it really knows I now have Windows 11 and is otherwise functioning as intended. Other than aesthetics then, is there any point of doing an uninstall/re-install?
That is interesting to know; obviously the different parts are reading it differently in your Windows System files.
As long as the functions see it as Win 11 then as you say what’s at the bottom is cosmetic, but still it should be correct.
Either that or the Win 10 is just a hangover from when you last did a full CCleaner install and hasn’t changed when you updated to 11.
All the ones that I’ve updated to 11 have been clean installs, and so a new CCleaner install too and not a carry-over.
However I haven’t heard here of anyone else seeing the same as you.
It’s up to you wherter do do an uninstall/reinstall or not.
Personally I would do one, it only takes minutes. There again I’m used to doing fairly often after changing my settings to try and replicate issues here.
Just another thought.
To check your Windows System files are OK you might want to run sfc /scannow (and if sfc finds errors dism /online /cleanup-image /restorehealth , then sfc again).
I uninstalled CCleaner, did a Windows Disk Cleanup and rebooted. Then I did a fresh install of CCleaner Pro. It still says Windows 10.
“… you might want to run sfc /scannow (and if sfc finds errors dism /online /cleanup-image /restorehealth , then sfc again).”
Not sure what all that is so I know better than to try it.
Of course you are quite right to be cautious about any recommended commands and apps that you are not familiar with.
It can be a security risk, or you could make a mistake if/when using advanced commands and tools.
In this case, sfc and dism are standard tools built into Windows for checking the Windows System files.
They are use millions of times every day by computer maintenance/service engineers and advanced users.
In particular sfc is one of the first things that anyone looking to fix a troublsome computer will run.
Here’s the Microsoft article about using them:
(That says to run dism first, but as dism takes time most people run sfc first to see if dism is actually needed).
If you google either one you will get much, much, more about them.
Bu fair enough, if you are not sure about using them yourself then leave them alone.
It’s puzzling how/why CCleaner is still identifying you system as Windows 10, it’s obviously picking that up from somewhere, but the functions like Software Updater are picking up that it’s actually been upgraded to Windows 11.
If you go to Windows Settings>System>About then what does it say there?
I also wonder which Windows version Speccy (also from the CCleaners stable) would identify it as being?
In the end though as you say your CCleaner appears to be recognising that you have Windows 11 and functioning accordingly; it’s just not saying that at the bottom for some odd reason.
Another thought does occur to me here.
Tomorrow is the monthly Windows ‘Patch Tuesday’ and at 18:00 UCT (7-PM British Summer Time) the latest ‘Cumulative Updates’ to Windows 10 and 11 are released.
It will be interesting to see what your CCleaner says at the bottom on Wednesday, following that Windows update.
