I would not remove RollBack Rx. It saved my bacon alot of times! I mean when it comes to using Windows System Restore and other back up solutions- I rather use RollBack Rx. Of course I also keep external back up in worse case scenarios but so far RollBack Rx is doing its job rather well. There is also a freeware called Reboot Restore Rx if you rather not spend.
