Get rid of removeWAT and get yourself either Daz's loader or a bios mod. RemoveWAT is a cool arternative but easy for microsoft to block and render it worthless.
I tried using Daz's loader but I kept getting things like "An Error was logged in the event log" when I tried to install software and "Unable to Achieve required system access" when attempting to use the Install Certificates and Serials, so I can't really use that. And how do I remove RemoveWAT, by restoring WATs or under the program list?
You say that with authority, yet you have no clue how it works. If you reinstalled Windows and just used its latest version you would have been fine. Versions 1.7 and 1.8 did that.
