I need help restoring my registry after using CCleaner


Recommended Posts

I used the registry cleaner feature a few days ago and it definitely messed up my computer: basically, there are times I turn it on and it turns off immediately. Also, many times it doesn't start Windows, it sends me straight to some weird Bios menu.

Anyway, I saved the registry copy when I did it, but when I right click on it and select "merge" to try to restore it I get an error message: "All data wasn't written correctly in the registry. The system or other processes have some keys opened or you lack enough privileges to do this operation". (I'm translating from Spanish, since my computer is in that language).

Any help to try to fix the mess that was made here??? Thank you.

I'm assuming this is Windows 10?

The Registry Cleaner (any registry cleaner)  can really mess up Windows 10 if used when not needed.

We recommend that you don't regularly use the Registry Cleaner with Windows 10, only use it if you have a specific problem.
Windows 10 changes the registry often which can give false results.
For the official Piriform advice on using the Registry Cleaner see this: https://community.ccleaner.com/topic/59952-i-get-a-registry-error-on-ccleaner-on-windows-10-i-have-scanned-5-times/?tab=comments#comment-326804

Here is Microsofts stance on using any Registry Cleaner:

That's the warnings done; now lets see if we can help fix things for you.

If you have damaged the regstry, and can't restore it from a backup, there are a few things you can do to repair Windows.

Let's go through them in the order I would use. NOTE than all of these options can take some time to do their thing.

Firstly, try using the DISM and SFC commands to repair the system image.
(Note that many articles, including the one I link below, say to run SFC first. That's just to save time, its always better to run DISM before SFC if you have the time because SFC uses the files that DISM updates, so doing DISM first takes longer but does make sure SFC is using valid and up to date files).

Open an elevated command prompt.
(That simply means: Open the Start menu and type "command prompt" when it brings up the command prompt options click on 'Run as administrator').

In the black command prompt window type the following command, (it needs to be exact so maybe copy/paste it), and then press Enter.

DISM.exe /Online /Cleanup-image /Restorehealth

It will take some time to run, and when finished should report 'The operation completed sucessfully'.

Now type the following and press Enter.

sfc /scannow

Again that will take some time to scan the system files and repair any errors it finds.
It will report if it found nothing wrong, or tell you what it has fixed, it may tell you to reboot if it fixed something.

Restart your computer (Restart not Shutdown) and see if things are back to normal.

 

If you are still having problems then if you have system Restore Points enabled  you can try restoring your computer to a point saved before you used the Registry Cleaner.

Open the start menu and type "rstrui.exe" (without the quote marks), click on 'Run as Administrator'.
That opens the System Restore dialogue where you can pick a Restore point and return your computer to how it was when that RP was made.
It's fairly simple to use just follow the prompts.

 

If none of the above has worked then we are looking at resetting Windows 10 and/or the Startup and Update repairs.
I'll not try to go through those step by step here, you can find them (along with what we have already tried above) in this article at options 4, 5,& 6:

PS. I won't try using Gogle translate to put all that in Spanish, there is quite a bit there and errors may be made by Google translate.

Worried about 'Tracking Files'? Worried about why some files come back after cleaning? See this link:
