*2 schools of thought on this one. Some think it's a resource hog. It will create a new restore point every time you install a new program. The restore point is as big as your amount of RAM you have installed. You can remove old restore points if you want as to not use up to much of your hard drive space.
I like it. before I do some kind of major hacking to my system or install some kind of beta ware, I create a restore point to return to if need be. Multiple partitions with multiple O/S's? Turn off System Restore on all drives except Windows XP's partition.
