Re: Thumbnails aren't showing 1k kumi if help
it's probably not spyware LOL
just rebuild the icon cache. I had plenty of problems with icons myself. Try what lub******** suggested. It could be a program, or it could be a bug in Windows. You can't do too much with the latter.
Finding a solution depends on how much you care about this. I'd try different icons, look for the ones which don't show up. If they're all from the same DLL or EXE, then it might be corrupted. Scan it with an antivirus that you have and if it's clean, look for it online and replace it. Or use a repair disk. Scan the replacement too, obviously. >_>
Also deselect "Hide extensions for known file types" from Folder Options, because you won't know what the files are otherwise. do this AFTER you restore the defaults, if you want to do that.
I'll be damned. So many of these solutions would just make matters worse.
