Yeah, when I said System Restore, I didn't mean that, I meant more of a System Recovery... basically a "erase everything and act as if the computer was brand new that you just unwrapped and turned on for the first time in your life", sort of thing.
I did try something that a lot of people have suggested, which involves disabling thumbnails... however, I'm not sure whether it's worked. Also, people say to delete the corrupted file, if there is one, but what if I don't know what is causing it? I'll have to just browse through random folders to see if I get a Windows Explorer message at all.
Also, on a somewhat related note, has anyone had the "stopped working" error with Winamp? I get that a little bit.
Oh yeah um... I did a very long 3-hour disk check: 0 errors found (to be basic)
A 1 hour, 40 minute-virus scan: 2 corrupt files in the temp folder but that had nothing to do with it (the error still happened)
A memory diagnostics test: nothing found
Registry check and other crap: 48 problems found, all fixed -- error still happened
I even did a defragmentation -- guess what? 2% fragmented... well, now it's 0% because of defragmented it
But, guess what? Windows Explorer again stopped working
So, if a virus scan, error checking, memory checking, other scans and everything you can think of doesn't work, and it turns out that simply disabling thumbnails is the solution, as someone said on Microsoft's forums of some sort "Seriously, Microsoft, release a ****ing patch already"
Oh yeah, apart from 20 random optional language packs, there are no updates available.
In other words, in terms of errors, viruses, registry problems, and whatever, this computers OK. The only error is um... well, you should know.
Oh um... er... this DID have Windows Vista when I bought it in March 2007, and then downloaded a shit beta Windows 7 in May 2009, and then upgraded to Windows 7 Ultimate on October 22, 2009 (the day it came out), but that shouldn't have anything to do with it, as it's only REALLY started like a week ago or so (it did happen a few months ago, but then somehow stopped until late November). Well, the thing to do is to see if the thumbnail fix actually did the trick.
