WindowsUpdate_8000FFFF ERROR

Posted on 2009-05-18
Last Modified: 2012-05-07
I keep encountering this error.  "WindowsUpdate_8000FFFF" no help in windows, does anyone have any

The help window within vista says "Help and Support
search term: WindowsUpdate_dt000" and when I use this nothing comes back.

At the moment Windows Vista wants the update KB929777 and can't have it.
Ends up with an 0x8000FFFF failure. Anyone know what that update is for
please? Is it urgent?
