80200001 is another failure which was seen along with 80240054 Neither of those codes is in the list . That's why you need to dig into the details in the manner I outlined. In the case of the first one its category isn't even there but guessing by 0x24xxxx being "success codes" maybe 0x8020xxxx is a new category of general failure, e.g. something more credible than "This should never happen", etc. Heh. Here is a more specific guess. Since 0x00240001 means 0x240001 WU_S_SERVICE_STOP WindowsUpdate Windows Update Agent was stopped successfully how about 0x800200001 may mean WU_ F _SERVICE_STOP WindowsUpdate Windows Update Agent was stopped UN successfully Again, avoiding speculation, dig into the details and find out for sure. Without access to source or support documentation, inference from all your diagnostics is all that we have to work with. HTH Robert

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?

Error: We couldn’t complete the updates, Undoing changes. Don’t turn off your computer.

Heh. Here is a more specific guess. Since 0x00240001 means

0x240001 WU_S_SERVICE_STOP WindowsUpdate Windows Update Agent was stopped successfully

how about 0x800200001 may mean

WU_F_SERVICE_STOP WindowsUpdate Windows Update Agent was stopped UNsuccessfully

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.
