80200001 is another failure which was seen along with 80240054

Find it in ReportingEvents.log. What does it say there? Find that event's timestamp there. Look in WindowsUpdate.log for that time. What does it say there? Look in CBS.log for that time. What does it say there?

Cumulative Update always seems to fail. Update KB3081455. Why?

Fixed all my problems! I bought a Mac Kiss off MS. Thanks to all on here for your help and good luck!

The 8.1 update failed without an error code(WindowsUpdate_dt000 OR 80240054). Just the statement "We couldn't complete the updates, Undoing changes. Don't turn off your computer." I went through all of the admin Command line commands before I tried to install the update, but it didn't help.
