Windows defender not updating wsus
If you’re seeing this error, it might be the case that your Internet connection is set as a metered connection, and that is causing issues with the Windows Defender updates.
Turning metered connections off is fairly easy, as long as you follow the steps below: If the issue is with your computer or a laptop/notebook you should try using the Reimage Plus Software which can scan the repositories and replace corrupt and missing files.
In previous OS versions the anti-virus client was replaced by System Center Endpoint Protection (SCEP) software when it was managed by SCCM.
To check this, you can head to the Security Portal and see if you can download the updates there.
However, there are a few things that you can do to fix this issue, which will let you install the updates again.
Try the methods in the order they’re written here, as they go from the simplest one to more complex solutions.
So, if I check for updates again at this point, it should say “There are no applicable updates.” However, it actually lists definition 126.96.36.199 again!
After that, it goes in an infinite loop: each time I install one of the definition updates, it asks for the other afterwards.
