Thanks for your help on this Joe. I decided to resize my max shadow space to
25GB, and my avail space on c: went from 22GB to 89GB! My shadow copy went
from 86GB to 17GB. I now have 4 restore points instead of 8, but I'm okay
with that. I still don't understand how your 7GB shadow space yields you 9
restore points and my 25GB shadow space only yields me 4 restore points. I
don't think I have an unusual number of programs, etc.

It's the size of the savings in Volume Shadow Copies. If you delete
all but the most recent restore point (if your system if humming along
fine, you should be OK), and start from "scratch" so to speak, you
should see an eventual improvement in the number of restore points.
