i would just leave it alone , it's not that big anyways , if you want to get more harddrive space then goto control panel > system > system restore > then disable system restore , you can gain up to 10 gigs that way
ya, I already have the system restore disabled. The thing is I dont have a very big hard drive, and I noticed the the windows folder doubled in size since I last checked it, so I investigated and found that folder and it is using a bunch of space. I tried to update to SP2 and it said that I didnt have enough space
