well…tried to do that using the directions for Vista (not on Windows 7) and received this (down below):
Thought about typing in:vssadmin Resize ShadowStorage /For=C: /On=D: /MaxSize=900MB (basically exchanging a D for the C in howtogeek’s directions, but thought I’d better check with you first, since this is waaaaay outside of my comfort zone.
Here is what I copied from the c prompt:

Resize ShadowStorage /For=ForVolumeSpec /On=OnVolumeSpec [/MaxSize=MaxSizeSpec]
- Resizes the maximum size for a shadow copy storage association between
ForVolumeSpec and OnVolumeSpec. Resizing the storage association may
cause shadow copies to disappear. If MaxSizeSpec is not
specified, there no limit to the amount of space it may use. As certain
shadow copies are deleted, the shadow copy storage space will then
shrink. MaxSizeSpec must be 300MB or greater and accepts the following
suffixes: KB, MB, GB, TB, PB and EB. Also, B, K, M, G, T, P, and E are
acceptable suffixes. If a suffix is not supplied, MaxSizeSpec is in
bytes.
Example Usage: vssadmin Resize ShadowStorage /For=C: /On=D: /MaxSize=900MB
