Have an HP G72 Computer, have been running with the original Windows 7 for over 4 years. Last November the 25th my computer had an automatic Windows update and was interrupted by a power failure, did not complete the update properly. Now I have a terrible time starting my computer and shows a message "This is not a Windows 7 Genuine Copy". Can this be fixed without formating the computer? Please help me as I have valueable information in the computer.
