Select the Properties for the drive that is using System Restore, and use Disk Cleanup to get rid of system restore points. The only drawback to this method is that all restore points but the most recent are deleted. I don't know of any way to delete points one-by-one, and I have wanted to do that myself. Another option is to change the amount of disk space that you will allow the restore points to take up. You can do this under System Properties-->System Restore. All this does is reduce the number of points that can exist at once.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
