@xpandvistafan I found the necessary updates: KB4467770, KB4019276, KB4493435, KB94228-V3. I hope it works after that. At least it worked for me afterwards.
I'm working on the issue right now. What I can say is that this update, which you already have installed, is necessary for the search to work. It looks like another update is missing.
Microsoft Update must be added manually. To do this, copy this file (muweb.dll) to c:/windows/system32 and register it with regsvr32. After that, the information bar should appear.

This is the same page. Unfortunately, this no longer works. I don't understand that https://fe2.ws.microsoft.com works and https://fe2.update.microsoft.com doesn't show the page. It's about the https. I think https://fe2.ws.microsoft.com uses other cipher suites
