Step 1. Try to uninstall the following update:

When you get the message: The update KB******* is not installed on this computer, then perform step 2.

Step 2.
1. Open a elevated command prompt and run the following command (to be sure that the COMPONENTS hive is loaded).

reg load HKLM\COMPONENTS C:\WINDOWS\SYSTEM32\CONFIG\COMPONENTS

Next fix.

Start the

Farbar Recovery Scan Tool again.

Warning: This script was written specifically for this system. Do not run this script on another system.

• Download the attachment fixlist.txt and save it to your desktop.
• Right-click on FRST.exe and select "Run as administrator".
• Press the Fix button.
• If for some reason the tool needs a restart, please make sure you let the system restart normally.
• When finished, a log called Fixlog.txt will appear in the same directory the tool is run from.
• Post the logfile Fixlog.txt as attachment in your next reply.

Afterwards try to install the Windows Defender feature again and post the result. If it fails attach a new copy of the CBS logs.

Is here a possiblility to learn how to read the CBS file correctly ?
If not, also ok ... Could you help me with the two others ?

strange, firsttime it works with wusa /uninstall /KB:4103720 ... I´m so happy, thank you for your support.

Great, even if the KB number is the same the issue could be differ on each system. But glad to hear all the servers are up and running again.
I will mark this thread as solved.
