Yeah. I'm stupid. I ran disk cleanup and made the mistake of compressing old files. Now my machine is running slow as Christmas, particularly when trying to open up saved Excel documents, Word documents, etc. Is it possible to un-do the compression? It's really driving me nuts and killing my productivity since this is my work laptop. I will be reformatting this thing tomorrow night if I don't find a solution. It's XP Pro, by the way.
