I don't believe that it is an error, I believe it's the extra filtering/protections in CCleaner browser that is your issue. Adblocking, anti-tracking, anti-fingerprinting, anti-phishing, stealth mode, webcam guard, extension guard, etc. Each one, if turned on, will slow things a little. It's probable that all that extra filtering in the CCleaner browser is just that little bit too much for the limited infrastructure that you have available in Namibia. As you say that you don't have the same problem with standard browsers, which don't have those filters, then that's probably the way you should go and forget using CCleaner browser for now. You could of course try turning off the extra filters in CCleaner browser so that it just becones another Chromium browser without the extra filters.

Webview2 can be a PITA for some users. It's needed by MS Office 365 and Outlook, but if you aren't using Office/Outlook then there is a way to uninstall Webview2 using a 'silent uninstall'. See this link: https://windowsreport.com/microsoft-edge-webview2-runtime/

The version numbers shown, although the same, are being parsed differently for some reason. It does sometimes happen with some softwares depending on how the version number is stored internally. CPU-Z does seem to be prone to it happening. (We saw the same thing happen with v2.01 of CPU-Z). I've flagged it up up for someone to take a look at and fix.

For licensing issues you will need to contact support There is an online form: https://www.ccleaner.com/contact/other-enquiry Or you can email them at: support@ccleaner.com

The system tray Icon is put there by one of two things, Smart Cleaning and/or Automatic Updating of CCleaner. Both need to run in the background if enabled and so Windows puts an icon for them in the tray if they are running. (They weren't enabled with the portable because it's meant to be on a USB stick and not on the computer all the time). As you've just installed then it's most likely the Automatic Updating but check both and turn them off if not wanted, they can both be found in Options. Once you've turned them off you'll no longer get that system tray icon.

Thanks for that, but I have removed your attached file. The posting executable files by anyone other than Staff/Moderators is against the forum rules, for obvious reasons. That 'Welcome' screen being shown more than once is a known issue that is being looked into. It is only affecting some users and not everybody. We knew that it was happening for some people with CCleaner Professional but yours is the first screenshot showing it in the Free version - so again thanks for that confirmation. The registry fix that was in your excecutable has already been given (not as an executable) in this earlier thread:

Possibly not so interesting. I now believe that @tachyis seeing a different version of the screen that is for the Free version. See here: https://community.ccleaner.com/topic/64358-ccleaner-startup-screen/ The fact that your CCleaners' are portable versions, but apparently on the machines and not a USB stick, may be having a bearing on your 3 machines? The portable version isn't meant to be used in that way, So any coding/development wouldn't take account of someone possibly doing that. (Is there any reason why you haven't gone ahead and deleted the portable.dat then installed them properly now that your hopes for the registry have been dashed?)

And yet the landing page message being discussed here is "Welcome back to CCleaner Professional". So if you are seeing it in CCleaner Free then that's very odd indeed. (And that might be a clue to what is going on). Are you seeing exactly the same screen as in the first post of this thread? Or does yours say 'CCleaner Free' at the top and then "Welcome back to CCleaner Professional" in the window?

Have you looked in the bin to see if there is actually anything in it? If CCleaner repeated says it's cleaning the bin, even though you have just cleaned it so it should be empty, then you almost certainly have a corrupted bin. Corrupted bins happen and are easy to fix: https://community.ccleaner.com/topic/60979-empty-recycle-bin-skipped-files/?tab=comments#comment-331053

Made me chuckle, there are plenty of 'tools' on social media I generally ignore them.

Each user account has it's own individual recycle bin. So if you are using CCleaner Free then it will only be cleaning one of the bins and not the other. As I said above: You need CCleaner Pro to be able to clean, or otherwise manage, multiple user accounts. PS. Although you say "every other app is works fine" you will find that things like word processors, spreadsheets, photo editors, etc. are now saving files in seperate places for each user account. ie. Each user has their own set of standard folders - Documents, Pictures, Downloads, and so on. Each user even has their own Desktop, and a user folder for that too.

As far as I am aware 'Ccsystem.dll' is a very old file that has not been used by CCleaner for 15 or more years. So I'm not sure why the uninstaller would even be looking for that. Unless of course you somehow had a very, very old version of CCleaner installed, or had remnants of a very old one on your computer somehow. Anyway: The first thing to do is to Restart your computer, not Shutdown but 'Restart'. (Restart clears more that Shutdown does, in particular it will stop that failed uninstall if it's still trying to run and preventing you reinstalling). Then try opening CCleaner again If CCleaner still won't open then download the 'advanced' Slim installer from here (3rd one down) and double-click it to reinstall a new CCleaner over the top of the 'broken' one. https://www.ccleaner.com/ccleaner/builds You may need to enter your key again after the reinstall so it's good that you have a note of it. Let us know how that goes.

I've never seen it on either of my two laptops. I do have the reg entry - it's off, and stays off. So while I can't try and test directly I can think of a cople of things. It's especially interesting for those who see it on one machine but not others, they have something to compare so may be better able to track it down. One thing that might be worth checking for those who see it on some machines but not others is if the CCleaner licence keys on each are older style (24-character) or the newer style (20-character, 3 groups of 6 plus the two dashes). Of course for Pro+ it may be the same key used on more than one machine. Which is another possibility, is it only happing with multi-machine Pro+? I can't think of any reason why any of that should make a difference, but when odd things happen you have to start looking for odd causes and ruling them out if you can. Looking at CCleaner itself has to be first, Windows can have too many oddities altogether. (For info both my laptops use an old style CCleaner key, same key on both). There again it may not be CCleaner at all but something subtly different in the Windows setup on each machine, or in user account permissions, or something of that nature. (Plus you can't rule out just what the user may be doing, we have seen in the past users changing things like firewall settings which then cause CCleaner to behave oddly because it can't connect to servers when it wants/needs to).

+1 for 'session'. As the name says it clears what you were doing in your last browsing session, which includes closing any open tabs.

Unexpected things can happen when creating new Windows user accounts, and/or when changing account permissions. In particular a new account/permission status may not be recognised by previously installed software. Is your CCleaner Pro or Free? If it's Pro then what do you have set for the users to be cleaned?

Which account is the Firefox installed in? Which account is the CCleaner installed in? Is your CCleaner the Pro version? You need CCleaner Pro to be able to clean, or otherwise manage, multiple user accounts.

It might have been better mentioning that you were in Namibia earlier. For all we knew you could have been anywhere in the world. (And your English is better than many Europeans, or even Americans, who post here). So yes, the lack of "up to date' infrastructure in Africa may very well have a bearing on your video streaming issues. Unfortunately services such as youtube and facebook are US based and so tend to assume that everyone lives in the USA with access to good infrastructure.

Mmm, you are aware that 3G is in the process of being switched off worldwide. I doubt that it has anything to do with your issues, but you never know. For instance your regular 3G broadcast mast may have been decomissioned so it's now having to connect to a mast further away and so getting a weaker signa? As for the other, if it's on a cororate network then there's not much you personally can do about that network. You'd expect an IT department to keep things up to date, but they do have time constraints and budgets just like the rest of us.

I think the blurry text is probably due to a Windows default setting, the 'transparency' effects can make text blurry when a browser page is loading or refreshing. It's not supposed to do that but it can do. Try turning it off: https://winaero.com/turn-on-or-off-transparency-effects-in-windows-10/ Freezing/stuttering/etc. when watching video can have many causes and can affect any browser. (In my Firefox Youtube will freeze the image for a few seconds, or loose audio at times). It's difficult, almost impossible in most cases, to track down just what the cause may be. As you say it affects multiple devices then I'd probably look to your broadband connection and your hub/router. When was it's software/firmware last updated? Most modern ones update themselves automatically overnight. If you are not sure then you could try switching it off or unplugging it from the power for a minute or two and then back on. That should clear any buffers that may be full and cause it to check for updates when it reconnects to the broadband. (PS. Don't do that too often, if you keep turning it off then the service provider thinks there may be a fault on the line and it will automatically cut your connection speed to compensate).

I do get it, I just wanted to translate it so that those without degrees in the latest business/marketing-speak and buzzwords can understand it without their minds boiling over. (Do marketing people get paid by the word these days?) eg. "a "container" for product use entitlements across multiple products and brands." I'd call that 'an account'. So I've saved about 300 words and come up with: ~~~~~~~~~~~~~~~ A group of related companies, Avast, AVG, HMA and Piriform/CCleaner, now share a common licensing system. When you purchase a product from one of them you get an account and key that can be used across all products that you may later purchase from companies in the group. The key is an 'account key' rather than a 'product key'. Your account has the information of what products you have bought from those companies, and when each product is licenced until. So if you purchase another product, or upgrade/renew a product, the entitlement to use the new purchase is simply added to your existing account. That saves having to have different keys for different products. ~~~~~~~~~~~~~~~ I believe that it's the email address that you use when purchasing that links you to your 'account'. (I can't see how else it would be done without asking if you already have one). And of course if they don't recognise that you already have an account then you will be issued another one, with a different, key.

A common key but with different expiry dates in different products, poducts which are from related but different companies. I think I need to read Dave's post another 3 or 4 times before I could even begin to try to explain it to anyone.

CCleaner is a cleaning tool, it wouldn't/couldn't fix a problem with broken com ports. (Neither would an anti-malware or anti-virus, they prevent/remove nasties they don't 'fix' other things). It sounds as if that Tune-up software has messed your com ports up (and who knows what else). It may have just turned them off - or it may have deleted a needed file or two, or changed/deleted a needed reg entry or two. Tune-up tools can be buggers for doing things like that, in this case then particularly if the tool you used is configured for Win10/11 and not for Win7. I suggest that you make a post over on 'bleepingcomputer' forum and ask for help there, there are knowlegable members who should be able to sort your com problem out. Here's a link to the Windows7 help forum there: https://www.bleepingcomputer.com/forums/f/167/windows-7/ PS. It helps if you can link a Speccy report to your post there so they can see what hardware etc. you are running. If you don't know how to do that then they can walk you through it if they want one. PPS. Also expect some friendly chastisement for using such a Tune-up tool in the first place.

Interesting. @MeganCCleaner can you shed any light on this?

The CCleaner trial is normally 14 days and you don't need to register, just download and try it. If you purchase a full licence then you don't use an email to register that licence - you use the license key that was sent to your email when you purchased. https://support.piriform.com/hc/en-us/articles/204043844-How-to-register-and-activate-CCleaner-Professional

If you have previously ticked 'Do not show me this message again' for a 'skip' popup then in future Custom Clean will simply skip it when necessary without showing you the popup again. It will just show 'skipped' in the results like it does there in your screenshot. And it's easy to forget that at sometime in the past you have ticked 'Do not show me this message again' for a particular item. So at some time in the past you have told CCleaner not to ask again about closing if Real Player 20/20 is running, so it's just been skipped. Presumably 'old' Real Player wasn't running so it got cleaned - or if you don't still have the older RP installed then it could be a glitch in the modified winapp2. Real Player and Real Player 20/20 are seperate apps and so it is possible to have both installed, do you have both installed? https://customer.real.com/hc/en-us/articles/360048296994-What-s-the-difference-between-RealPlayer-RealPlayer-20-20-RealPlayer-People-Search-StarSearch-by-Real-RealPlayer-Discover-RealPlayer-Downloader-RealTimes-RealPlayer-Cloud-
