1. Click Start – All Programs – Accessories. Right click on ‘Command Prompt’ and click ‘Run as Administrator’.

2. Type the following in the command prompt:vssadmin list shadowstorage

3. If you feel like Vista is taking up too much space, then use this command to lower it:vssadmin resize shadowstorage /On=[Drive Letter]: /For=[Drive Letter]: /Maxsize=[space]For example, I executed this command to lower it to 2GB:

vssadmin resize shadowstorage /On=C: /For=C: /Maxsize=2GB 

Just another way of doing it…


1. Click Start button.

2. Type clean in the Start Search box.

3. Click Disk Cleanup from the search results list.

4. Select Files from All Users on this computer option.

5. Disk Cleanup will perform calculation to determine how much space it can free. Once done, click on More Options tab.

6. Under the section of System Restore and Shadow Copies, click on Clean up… button.


Also System restore in Vista takes huge space to store restore points. This is also Windows’ regular process. Kindly guide this customer to turn off system restore or to limit the space for system restore :-

1. Right click on Computer then select Properties.

2. In the left pane, click System Protection.

3. You will see a list of hard disk drives installed on your system, with checkboxes to the left. The check boxes with tick indicate that System Restore is on for that particular volume. So to to turn off System Protection for a hard disk, clear (untick) the check box next to the disk.
