Have patience with the the Dell recovery, recovery and/or repair can take time - but if that fails to work and you still can't get to the login screen then you can get Windows 8.1 into Windows own Automatic recovery/troubleshooting mode by doing what is known as a 'Hard Boot' This simply means turning you computer on and then off again to interrupt the boot 3 times in a row, at which point Windows recognises there is something wrong and when you turn it on the fourth time it should start it's 'Automatic Repair' procedure. Again it will take time to diagnose and try to repair whatever the fault may be. See number 2 here for how a Hard Boot and Automatic Repair works: https://www.digitalcitizen.life/5-ways-boot-safe-mode-windows-8-windows-81

You used Health Check from what you say, that's fairly basic/non technical and should not have affected your boot. If you didn't click on Reg Cleaner then you didn't run it. It is just slightly possible that the 'Speed' section of Health Check may have removed something that a Dell uses at boot of 8.1, but if so then yours is the first report we have seen of it. The message about an instruction not being accessed makes me think this might be a memory chip/disc problem at that physical location. They can happen, and when they do it"s usually while you are updating some software. Is your machine bootable or can you not get to the desktop at all?

Which version of Windows? Win 10 doesn't use the f keys to get in to safe mode - it boots from the BIOS too quickly to be intutrupted with a key press. https://support.microsoft.com/en-gb/help/12376/windows-10-start-your-pc-in-safe-mode Did you use CCleaners registry cleaner? If so did you make a backup when it asked?

I still have a box running 98SE, and still use it a couple of times a year. I keep it because I have the full version of AutoCAD 2000i on it. - You can't buy Autocad outright anymore and a monthly (£234) or yearly (£1,890) subscription costs way too much for occasional use.

A number of posters would disagree.

Good things just keep going despite flood, fire , or plauges.

The usual answer will be that Beta versions of OS/software are not supported. (It's the same with Windows insider betas). It is possible/probable that things in a beta will be changed before final release, so developers of other software don't chase after those changes until they make it into the full release. The recent Firefox database change was an example, the CCleaner developers knew about it but didn't change CCleaner until the change made it out if the FFx beta and into the full release.

I hadn't noticed that, it always used to save it to Documents but now it seems to default to the Desktop. You can change where it save it in the dialogue that comes up. TBH don't use the Registry Cleaner, it's not needed these days unless your computer has a big problem/very damaged registry. Windows will usually sort out any registry problems itself these days. https://support.microsoft.com/en-gb/help/2563254/microsoft-support-policy-for-the-use-of-registry-cleaning-utilities

May be preaching to those who already know but - When searching for something like that then try putting your search string in double quotes, eg: "is damaged and can't be opened" will get more focused results than: is damaged and can't be opened

Recent Files show in Quick Acess if I turn it on, but I don't want to see recent files in Quick Access so have left it turned off for now. If I remember correctly I originally turned it off in the reg editor. I've not tested if closing FE removes the recent files for me, that's a bit remiss of me but I've had beer and wine (friends birthday) and prefer to do any testing with a clear head. Of course that is not helping hsl so I can turn it back on again for testing if needed - once I'm sober again.

Yes, sorry about that. It was one of the first that I dropped on, and TBH the others I read were even worse. At least it worked for you which is always good news.

Apparently that error is quite common with Mac's, and fairly easily fixed: https://blog.verslu.is/development/appnamis-damaged-and-cant-be-opened-you-should-move-it-to-the-bin/

#1,3, & 4 were what I was having no success with, #2 was the setting stopping them.

That is what we are trying to work out; just why this is happening for you. Like I say, I am stuck - I can't even try to test things because Windows will not let me keep the "Recent files" list in File Explorer Quick Start at all. And I'm not sure why Windows won't let me keep that list; but I am sure that is Windows doing that and not CCleaner. It may be a Windows setting that I have changed in the past and forgotten that I had changed it? (It is the kind of thing that I may have done because being used to 40 year old computers I sometimes work in a different way with recent files). As Hazelnut can still see the 'Recent Files' then maybe she can work out what is happening for you.

Thing is that I have not run CCleaer at all, I've not even opened it. So what I am seeing seems to be Windows itself.

That's the one that I'm meaning. Frequent folders stays on for me but not Recent files. As soon as I close File Explorer then Recent files has dissapeared altogether when I open it again. I am on Win 10 2004.

I'm wondering if it is Windows itself that is removing them? I can't get Quick Access to even use the recent files list. I set it to on but as soon as I close file explorer Windows resets it to off. Hsl, if you leave file explorer open showing the list, and run CCleaner with that window still open then do they still dissapear?

As Hazelnut asks, but also: Which app is the recent file list being removed from? Note that the unticked item you show is for Windows Explorer, (File Explorer), if the recent list is being removed from another app then it may be a different setting that you need to untick for Custom Clean.

It's not clear why that blank screen ocassionally happens, it seems to be an issue with the offer sometimes not being able to be fetched from the server. That could be because of some glitch at the server, or some glitch with your broadband service. When it does happen it's normally only temporary, and if you try again it works without problem. But if it keeps happening repeatedly to you then it could be (probably is) a firewall setting in your antivirus or other security app. In that case using the Slim installer almost always works. Rebooting in Safe Mode should also work, as your antivirus would not be active in Safe Mode. (And you have no internet connection anyway unless you have chosen Safe Mode with Networking). If you have a laptop switching Flight Mode on will also block the internet connection and should then let the Standard installer work. The developers are trying to track down what causes it, (apart from the firewall settings), but it happens so infrequently that they can't replicate it to test, and until fairly recently nobody had even managed to capture a screenshot. If it's a temporary glitch in your broadband service then it will be beyond their power to fix anyway. I've only ever had it happen to me once, and I'm always installing/uninstalling CCleaner to test things out for this forum. I probably install it 10 to 20 times more often than a regular user would.

There are two ways to do that: You could identify the cookies for the sites in question and move them into the 'Cookies to Keep' section. See this for more information on how to do that: https://www.ccleaner.com/docs/ccleaner/ccleaner-settings/choosing-which-cookies-to-keep Alternatively you could untick 'Cookies' for every browser that you use so that Custom Clean will not delete any cookies at all. Those settings only apply to Custom Clean so from then on only use Custom Clean because Health Check will still delete those cookies and so log you out of the sites. Note that some websites will log you out automatically after a time idle anyway, it's a security measure.

The Defender registry entries will be protected so that malware can't alter/delete them. 'Controlled Folder Access' in Defender has always been a bit of a PITA. When they first brought it out you couldn't even save anything unless you were using a Microsoft app (ie. Office). Took me a few hours to work out why my (not Microsoft) word processor wouldn't save anything, I eventually worked out it was because the defender CFA wouldn't let it delete the previous .bak file to make a new one. It looks like that registry entry is saying that CCleaner is one of the (not Microsoft) apps that is allowed to save and/or delete things. It will be Windows that is keeping it there as an 'Allowed application'. It knows you have once had CCleaner installed so has added it to the allow list. If you no longer have CCleaner the reg entry will maybe/probably be removed in the next Windows feature update? ( or maybe next Patch Tuesday?). But maybe not - Microsoft programmers work in mysterious ways.

No problem, happy to help. It looks like you fell into a bit of a gap in how the update from the trial is supposed to work, but there is usually more than one way to do things. I think the programmers realised that when they gave that 'Downgrade to free' option as a way to 'begin again'. (If that hadn't worked then the next step would have been to uninstall CCleaner trial and really 'begin again' by installing Free and upgrading). As for speed of response, you fell a bit lucky that one of us regulars was online to help fairly quickly. We are users not employees, so we are not here 24/7, we do usually pop in at various times during the day but it make take a few hours/days before someone can answer a particular question.

OK, I've not seen that particular screenshot from the trial before but it looks simple enough. 'Continue using Professional' will take you to the purchase page - Which you don't need as you have already purchased a licence, so - As you have already purchased a Licence Key then on that screen click on the 'Downgrade to Free' at the bottom, once it is downgraded to Free then follow the steps as I gave them above. If that still won't work then come back and we can try another way.

There is no need to download again. You can simply upgrade the Free version to Pro by doing the following: In CCleaner (Free) go to Options>About and click on 'Upgrade to Pro'. Enter your licence key (and name if it asks) when asked, and then click on 'Register'. (Don't click on Purchase or you will be taken back to the purchase page). PS. Be careful if typing it in that you don't mistake numbers/letters (eg. 5 & S), and If copying/pasting your key from the confirmation email then make sure there is no leading or trailing blank space. Those are both common errors that can cause registration to fail. Once registered as Pro it will remain so for any updates, until the licence expires. If for some reason it does become 'un-registered' again simply repeat the process to re-register it. For more in depth information about registering see here, but you shouldn't need it if you do the above. https://support.piriform.com/hc/en-us/articles/204043844-How-to-register-and-activate-CCleaner-Professional

CCleaner would not/should not delete any emails. Could you tell us more about what you are seeing happening?
