Windows 7: CCLeaner & 100% CPU Usage

CCLeaner & 100% CPU Usage

Hi All,

I've found lots of great info on here browsing through other threads on numerous things, and I've got a quasi-original question.

I downloaded and installed CCLeaner and ran both the cleaner/registry cleaners. Now all of a sudden windows explorer keeps resetting itself, not responding, icons refreshing, and overall running like crap. Whenever I right click on anything in windows explorer it freezes up, stops responding, and I have to close it out.

Any ideas what CCleaner has done to screw up my computer?

p.s. for reference I'm running Windows 7, 4gb RAM, Intel Core2 Duo CPT T7300 @ 2Ghz and it was running great prior to CCleaner

Do you still have system restore enabled on your computer? You could try a restore point prior to running CCleaner.

I know lots of guys swear by this app, but I don't usually recommend running tools like this (even the almighty Ccleaner from Piriform), especially the registry cleaner portion. The only time I run this is when I have exhausted my other outlets and a reformat/reinstall has become acceptable to me.

1. Did you create a backup before you ran CCleaner? If so, just restore the backup.

2. If you didn't create a backup use System Restore to a point before you used CCleaner.

3. If it was me, I'd unload CCleaner and forget about third-party registry "cleaners" as Windows 7 seems to do a pretty good job on its own.

As you said yourself, your computer was running great before you used CCleaner............if it ain't broke...........?

Are you absolutely sure it was CCleaner? Countless people on these boards have been using it for years without issue. The issues you describe don't sound like what I'd expect if registry entries were missing. You could also try running sfc /SCANNOW from an elevated command prompt.

Without turning this into another debate, Windows doesn't clean the registry on it's own, so it can't be compared to CCleaner. Let's also skip the debate on cleaning the registry, as it's been well demonstrated and documented on here when that is useful, and sometimes the best/only solution to a problem.

Point taken as starting an argument about CCleaner was the last thing on my mind.

My choice of words was perhaps a bit unfortunate, but I was trying to make the point that if things are running fine it's best to let them run without interference.

I perhaps should have mentioned that I had a bad experience with CCleaner last year on my Vista rig and I haven't used it since.

But, as you quite rightly point out, many people are happy to use it.

As Deacon suggests, running SFC /scannow from a command prompt is not a bad idea.

Some people have problems, some people don't. I have seen too many random, seemingly arbitrary problems go away with the removal of CCleaner and other registry/cleaners of the like to assume coincidence. It's the last thing I will suggest with windows 7, and one of the first I will suggest to get rid of.

Excellent. I still have flashbacks and scars from the last one, until I was able to give examples of when it helped me out.

I'm still not convinced that is the issue here. Usually, if something in the registry is deleted (that was needed), you'd have problems opening files of a certain type (or programs in general)...or you'd have random error messages popping up.

The real issues arise when the knowledgeable convince the less-so that these apps are ok to use and they end up like this; for people that really know, they can be used safely but they should not be recommended to casual users, even CCleaner can ruin a system.



@astarrb, it may take running the sfc /scan several times to completely repair the system files.

Thanks for all the replies everyone. I'll run sfc/SCANNOW and see what happens. Is there a way to save multiple restore points? It seems like I can only access the latest one (right before CCleaner) but if it makes another one I won't have access to the one prior to CCLeaner.

Thanks!

I was constantly getting BSOD until someone on this board told me to try a registry cleaner. Its been a year now with no more BSOD. Always create restore points though.
