There are a number of these threads around the web, but none solved my problem. I found the solution in Vista itself, after ransacking Technet.
My problem: I had about 65GB of files on a 178GB HDD, but Windows and many other ways of looking at it showed only about 10GB of space available.
My solution: a program in Vista called vssadmin.exe -- the command-line admin program for the volume shadow copy service. Open a cmd window and type "vssadmin help" for details.
I ended up using the program's "Resize ShadowStorage" command to reduce my shadow storage from over 90GB (the max parameter was set as "unlimited") to 7GB. The smallest number allowed is 300MB, so I thought that would be enough. Does anyone think it isn't enough? Or too much?
One thing I had to learn by trial and error: the Resize ShadowStorage command shows you where shadows are made from and to. In my case, both were the C drive, but with a long string to identify the volume. I just used "C:" as the parameter in both for and to, and it worked. I regained almost 100GB in an instant. Very satisfying.
Hope this helps someone else.
