I use it for having a "known good" state for my Windows VMs - that way, 
if things get hopelessly screwed up, I can go back to a state where 
things are known to be working.

I usually apply patches/updates (antivirus and the like), reboot, let it 
run for a little bit to see if there are any issues, and then merge the 
snapshot in with the base, shrink, and then take a new snap.
