Maybe not help exactly, but this is often the sort of experience that drives home the importance of backups to most people, so make sure you're among them. Also, this sort of thing is typically a sign of there having been, and quite possibly still being, some kind of malware infestation. So in a sense, it's kind of a blessing in disguise by rooting out something that may have been silently lurking on your computer for who knows how long, and doing who knows what. The silent ones are often the most dangerous.
So as you may all know, Windows 7 officially started to have Service Pack 1 start to automatically install on March 19. So it just installed for me last night (without my permission)... and It screwed me good and hard. I have lost pretty much every single preference on my computer.
Browser bookmarks, teamspeak bookmarks/preferences, wallpaper, every single desktop icon that isn't a shortcut to a game.
And, worst of all, every single file/folder I had on my desktop. Gone. Just gone. I was a lazy guy and my desktop was COVERED in files. Over 100GB I would wager.
Is there any way to reset any of this? Are the desktop files stored anywhere? Is Service Pack 1 supposed to do this? Any help would be greatly appreciated.
