Hi everyone. My problem started about 2 months ago when I installed Vista Ultimate 64 bit and Service Pack 1, after using Vista for about a week my free space went from 200gb to 130gb. I ignored this as I thought that it was just one of Vistas many bugs. About a month after that I installed Service Pack 2 and my free space went up to what it should be (200gb), but then after about a week it went back to 130gb. Then yesterday (Saturday 31 October 2009) I installed Windows 7 Ultimate 64bit (by choosing the upgrade option) and the problem still remains. Any ideas on how to fix this?
