I did this and no damaged files were reported, I restarted and had to wait again for 20 minutes for this Microsoft Registry Checker to run. When it is "Rebuilding System Registry" it gets to 75% like before and gives me that same error message. HOW do I stop the Microsoft Registry Checker from running ???? Nothing was wrong before except the comp was running a bit slow now I have to wait 20 minutes just to get online.
