They claimed it wouldn't but it did actually run to completion the native Windows defrag. Where their claim came from was a few files that were left alone. This bothered the member to no end and they posted dozens of posts about it with most replies telling them not to worry about it.
I wouldn't give it another thought, set it to defragment once a month on it's own and go back to enjoying the PC.
Hey guys for the longest time my laptop(xp) wouldnt defragment. It would always say that i didnt need to even though i knew it needed it. I upgraded my ram to 2 gb from 1 and now it defrags. why did it not before and it does now? ps im using window washer which is pretty much the same thing as cc cleaner. does the use of this program have anything to do with it? thanks
