Rapidly Losing Hard-Disk Space in Vista?

We recently had a problem with Windows Vista... the hard-drive was rapidly filling up. 30 Gigs of free space on the disk disappeared within a week. The drive was full, and windows was giving the 'low disk space' error messages. I deleted 10 gigs, which filled up again after only 2 days...the same error messages returned.

Here's the solution to freeing up disk space in Vista

Vista uses a large amount of disc space for system restore and for shadow copies. To limit the amount of disc space allocated to system restore and shadow copies, open a command window by right clicking and selecting "Run As Administrator". Copy and paste this line:

vssadmin resize shadowstorage /On=C: /For=C: /Maxsize=2GB

Press enter. This will limit the space used to 2 gb but you can set the maxsize value to any number although I wouldn't go any smaller than 2 gb. Doing this will not reclaim all of the additional used disc space as there other reasons for the disc space usage but in my case it freed up 37 Gigs of hard-drive space.
