Q: I understand that Windows Vista makes it possible to delete ALL restore points except the most current. But, I would like to be more selective and control the amount of restore points. The problem I'm having is the amount of disk space that Vista is allocating is currently over 30GB. There must be a work-a-round of some sort for this?

A: By design, Vista will not allow you to selectively delete your restore points. This is because each one relies on the other for proper functionality. However, you can control how much disk space to allocate to Vista for these restore points. Here's how:

1. Click the Windows button.
2. In the search field, type: cmd
3. Right click the "cmd" item and select "Run as administrator" from the resulting menu. Click OK for any User Account Control prompts.
4. Once the command windows appears, type the following exactly as shown, press enter when done:

vssadmin list shadowstorage

The above command will list the current amount of Used, Allocated and Maximum allowed storage size for the Volume Shadow Storage on your computer.

To resize the amount of disk space that Vista allocates to shadow storage, type the following exactly as shown, press enter when done:

vssadmin Resize ShadowStorage /For=C: /On=C: /MaxSize=2GB

You should get a message that states the command was successful.
The above examples assume that the root drive for your system is C:
To change the maximum allocation, replace 2GB with your preferred amount (eg: 400MB or 4GB).
