I have run into this same issue recently, and the culprit is the fact
that large numbers of System Restores are being written, as I am adding
software after yet another reinstall of Vista 64 Ultimate. On my system
the restores were consuming more than 15GB of space (estimated, as Vista
hides the size of the folder in which the restores are kept) on a 120GB
drive (which loses more than 15GB with an HP factory recovery partition,
a hidden QuickPlay partition, NTFS formatting, etc.).
The slider for the the Restores size that existed in XP isn't found in
Vista, for whatever reason I don't know, other than MS being bound and
determined to get as much control away from users as possible. As
usual. And the "fix" is to go into Disk Cleanup and blow away all the
Restores but the last one. Which is stupid. But that seems to be Vista
x64, the "ultimate" OS.
I find it amazing that in using Vista the need for command line inputs
seems to be 10x that of XP. Why, oh why?
So...to change the size of the system restore space allocation, and
free that space back up for the drive, you have to do the following:
From a command prompt:
vssadmin resize shadowstorage /on=c: /for=c: /maxsize=4GB
(I used 10GB, which on my system saved the last 13 restores)
There are a number of how-to-pages on the Web about this, this is the
one I used:
'Change the System Restore Size in Windows Vista'

I hope this helps...maybe. Good luck.
