CCleaner killed my computer


Recommended Posts

Hi. I used CCleaner on one of my computers roughly last week-ish, in an effort to speed up my computer on startup, but what it did was kill my wifi, sound, and I can't install ANYTHING on my computer now. I feel like I have to reinstall Windows again. What can I do? Thank you.

I ran the most recent version of CCLeaner, and I use Windows 7. And yes, I think I did run the registry cleaner, IIRC.

Did you also delete anything in the Tools>Startup section?

Did you make a backup of the things you deleted when offered the chance to do so by ccleaner ?

 

Have you tried system restore to a time before you used ccleaner ?

 

What antivirus do you use and are your scans up to date and clean?

 

What problems were you having in order to make you try to use something (ccleaner) to 'fix' it?

Can you post some error messages you're getting? How exactly you can't install anything?

As hazelnut asked, have you scanned your PC for viruses/malware?

Have you had any bluescreens?

I am trying to get my wifi back up, but it won't let me install ANYTHING. It just gives me a message that says it can't install.

 

Yes, nothing came up, but even the anti-virus software won't work due to the connection being cut off.

 

And no, no bluescreens. I'm not getting any error messages.

Since you are having a problem with Internet Connection. I suggest that go to Device Manager and uninstall the network adapter but, make sure NOT to check 'Delete the driver software for this device' (a snapshot is attached). After uninstalling the network adapter, scan for hardware changes and it'll reinstall the network adapter.

 

 

 

There is no way that CCleaner's Registry Cleaner can harm Windows. Even by deleting all the Startup entries, there is no harm to Windows. CCleaner is a very safe program.

 

I suggest that install Auslogics Registry Cleaner and run it.

I'll try that. But as I said, it may not install as my computer won't let me install ANYTHING there.

That can be the problem with INSTALLING software.

Normally I expect to bypass that problem altogether by use of a PORTABLE version.

 

You are probably in luck with either

This is really weird.

 

You said you have a Windows 7 system...right? is it 32-bit or 64-bit?

 

Create another user account with Administrator rights. and see if it solves the problem.

 

I feel you are having a problem with User's Administrator rights.

That is rather bad advice IMO :huh:

 

This program runs with Administrator rights ONLY. This way atleast you can find out if there is an issue with User's Administrator rights. :)

 

BTW all the name brand registry cleaner programs like this one, Ace Utilities and Registry First Aid runs in Administrator mode.

You can reset Windows Security settings to its defaults by using the command listed here:

 

Run Command Prompt as Administrator

 

secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose

This is an oldish thread (2009), but it's the same problem you're experiencing ...

 

http://windows7forum...4.html#post8110

 

The link in the above post leads to another website which has posts from a lot of individuals fixing the problem with the small registry edit ...

 

http://social.techne...c-c15d0ee850ec/

 

The above link comes from a long page of posts with no post numbers, and the relavant post is the second on the page under "answers".

 

To see that particular post in context, and the posts following it, you'll have to scroll way down the page.

 

It may not be of any help to you, but read down through the posts following the one I mention, and there may be something you could use.

 

In fact, although it's long, a read of the entire page may be worth your while.

Regarding the system restore as well, it gives me the following message: "A volume shadow copy service component encountered an unexpected error. Check the application event log for more info. (0x80042302)"

 

It looks like the Restore points got corrupted. I have tried R-Wipe&Clean program. It deletes Restore points without any warning. There is another program East-Tec Eraser and it warns before deleting the Restore points. I am not sure about CCleaner.

travelingig I am coming round to believing that ccleaner was not the cause of your problem, you say you didn't see a prompt to back up the registry so you may not have even done a registry clean anyway. You had problems even before you ran ccleaner you say.

 

if you read the pages DennisD linked to they have the same problems but there are many different causes. Windows seems to have gotten itself in a twist in your case.

 

Did you make a system repair disc when you first got the computer?

 

Have you tried running a system file check? (option 2 in below link)
