    Have you used a Restore point recently?

    This article references to Vista but one of the error codes is the same.

    Error message when you try to install a Windows update, a hotfix, or a service pack after you perform System Restore in Windows Vista: "0x80071A91"

    No, I have not used any Restore point at all. In fact my laptop is quite new, about 4 months old.

    Thanks

    Further reference material to read through,

    You receive error code 0x80070643 or error code 0x643 when you use the Windows Update or Microsoft Update Web sites to install updates
