Cleanup System Restore
System Restore is a part of Windows that you can use to restore your computer to a previous state if a problem occurs. System Restore monitors changes to the system and creates restore points automatically. Once your system has been running stable for a while, you can delete all restore points except the last one in order to recover disk space.
To do this, Start Disk cleanup which can be found by navigating the following; Start Menu > Programs > Accessories> System Tools > Disk Cleanup. Once the calculation has finished, go to the “more options” tab. In the system restore section, Press the “Clean-up” button, then ok to continue.
Note: Do not delete restore points if your system has been unstable recently.http://computercleanup.blogspot.com/2006/1...em-restore.html
