Service registration is missing or corrupt

After days of trial and error, this did the trick for me:

1. Open command prompt and type "NET STOP WUAUSERV". This will stop the spazzing Windows Update Service.
2. Follow up with typing "WUAUCLT /DETECTNOW". This will detect, download, and process all necessary updates behind the scenes. Depending on how many your system requires, this could take A LOT of time. I had 110 updates needed, so it took a while.

Is this a permanent fix? Probably not, but it should get you up to date on all critical updates released at the point in time these commands are run (hopefully).

its not working and u see my problem is same as u but it didnt work . so plz use screen shots to tell for taking a screen shot press windows button and then prntscr

The problem I have is with KB33124200 and I copied the DISM tool line, ran it in an elevated command prompt changing the KB to the one I am having trouble with; and it can't find the update.  I've run WU six times in the past week and I still run into problems.  My fix-it shows that the service registration is missing or corrupt.

I am on Windows 10 64 bit, and it was formerly Windows 10 32-bit.  There aren't any extra profiles; it updated itself to 1511 and now can't run the cume updates.

Your problem is at the command prompt. "wuaclt /detectnow" should not be there: Copy the command line immediately following the prompt. If copying the line is a problem then manually inserting it should work.

I ran this cab as directed and it failed to "open".
