Reduce the space used by System Restore in Vista from command line

If you're new here, you may want to subscribe to Windows Reference RSS feed Thanks for visiting!


The System Restore feature is built into Windows vista and is used to return your computer to an earlier state if you have a system failure or other major problem with your computer. The point of System Restore is to restore your system to a workable state without you having to reinstall the operating system and lose your data files in the process.

System Restore can use up to 15% of a hard drive for its backup files (shadow storage). As hard drives get ever bigger, that becomes a lot of space. The command “vssadmin” can be used to administer settings for System Restore. To control the space allocation, open a command prompt with administrator privileges and enter

vssadmin Resize ShadowStorage /For=C: /On=C: /Maxsize=[n]

For [n] enter the desired size in MB or GB. The units must be stated: for example, “Maxsize=500MB” or “Maxsize=2GB”. The example is for the C: drive.

WARNING! This will delete all your old Restore Points!
