How to fix error 0x80070490 so windows 7 sp1 will install
Have tried for several days to install SP1 on Windows 7 Ultimate. Ran/installed System update readiness tool, ran the CSC log, ran the windows update troubleshooter and still no luck. Last update received was at 8:42 pm (PST) for KB978821. Please help if you can.
