System Restore

System Restore in Vista is a lot more complex than it was in WinXP. Vista has a shadow copying feature which automatically saves previous versions of files you create. The amount of space set aside for System Protection (new name) is shared with Volume Shadow Copy. This is a pretty significant amount of space though, basically 15% of your HD space. If you have a small HD that is typical of notebooks, then you might want to reduce the size of this space. The problem though, is that it's all or nothing. You can turn off System Protection and recover all the disk space, or leave it on and give it 15% of your space. There's another way though. You can use the command prompt to reduce the size of shadow storage. That way, you still have System Restore and Shadow Copy protection, although not as much. Try the following:

1. Open command prompt by typing in "cmd" into Start Search.
2. Use the following command: vssadmin resize shadowstorage /on=[drive letter]: /for=[drive letter]: /maxsize=[maximum size]

For example, if you want to drop the size of system restore and shadow copying on drive C: to 2GB, you would use:

vssadmin resize shadowstorage /on=c: /for=c: /maxsize=2GB

The following abbreviations are used for disksize, KB, MB, GB, TB, PB, EB. The minimum size though, has to be at least 300MB. Since minimum size is 300MB, I don't know why they even bother to have the KB option. I'm also guessing that that PB (for petabytes) and EB (for exabytes) are not really going to come into play anytime in the near future.

The change is instantaneous, you don't have to reboot.
