Man you did it again sfc /and checksur looks good now I am trying to run the updates and got error c8000266 I will try it again and let it run and see what happens . now that the sfc /cheksur is good I will create a system restore point and a registry backup , so when I run into trouble I can always come back to this point in time that my computer files and registry was straight. please tell me the difference between the sfc /scannow and the checksur scan. Thanks Brilliant Brian.
