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

After much research I discovered the problem is not resetting the clock before any downloads or updates. This is the fix that has worked for me up to now. I went to updates and reset in the control panel and reset my computer without saving any setting.

After that is complete it will ask the do you prefer English and time zone questions.  Answer all this as normal until you get through them all.

Before doing anything else. You should be at the desktop.  Go to the clock setting and click on automatic update and reboot your computer.  When booted back up check the time and date and time zone again. You may have to force it to the correct time zone.  I had to.  

Next step go to control panel and check for Windows updates and let that run everything before you download anything.

What happening is the time zone stamp on the licenses is incorrect and spits out an error.

After letting windows update robot and when you go to the windows store it will check lines and allow you to download them.

It's really kind of stupid because the windows store already says you own them.  Why not check the licenses and if they are cirrupt, replace them with a new copy.

From recently I can't update windows and I ran MS Fix it Center and it shows that service registration is missing or corrupt.

I running  Windows10 enterprise, and ran the update troubleshooter, and it still came up with " Service registration is missing or corrupt

What do I do ?

I have been on to samsung with the same problem,my machine was not compatable with windows 10 so when i uninstalled it,it deleted the service registration and the only way to get it back is to send it back to samsung to be reinstalled at the cost of seventy quid.

I finally solved this issue uninstalling all .NET Frameworks.... at restarting, Windows update .NET and everything is working ok again.
