+ 0 Votes Did you happen to save a restore point? wizard57m-cnet Moderator April 6, 2013 at 7:58am PST Prior to making all the changes, if you saved a restore point, use Backup & Restore to return the PC to the state just prior to your changes. Other than that, you may need to boot from the XP installation media and choose a repair installation. + 0 Votes Reponse To Answer StealthRider April 6, 2013 at 10:20am PST No, system restore depends on RPCsS so it wouldn't work. I was almost ready to do a reinstall good thing I didn't have the discs, before I was going to order them I decided there HAD to be a fix and I kind of knew it would be easy if I could just find where the change resided. Since it affected almost everything I knew it had to be in one place! I resolved by deleting the registry "LEGACY_RPCSS".
