Cleaning up after Vista SP1

While you might not be doing this just yet... (since Service Pack 1 just came out and there might be fun things that just break due to it)... at some point you're not going to want to restore before pre-SP1.

When that day comes, then you'll want to know to run vsp1cln.exe from the command prompt.

When you do this, it'll get rid of the restore versions of the files that SP1 replaced and you'll save some valuable disk space. Just remember that the wipe means you won't be able to go back anymore so make sure that's exactly what you want to do before you go do it.
