HOW-TO: Import Out of Band Updates to WSUS using Microsoft Edge Chromium IE Mode and PowerShell

Karl-WE 

I added both sites to our IE Compability mode lists for Edge.

  <site url="catalog.update.microsoft.com/">
    <compat-mode>IE11</compat-mode>
    <open-in allow-redirect="true">IE11</open-in>
  </site>
  <site url="catalog.update.microsoft.com/v7/site/Home.aspx">
    <compat-mode>IE11</compat-mode>
    <open-in allow-redirect="true">IE11</open-in>
  </site>

Using this, I get an error  "To use this website, you browser must have the user data persistence setting enabled." I also added Windows Update Catalog to Trusted Site Zone list. In Trusted Site zone list, I have Userdata Persistence turned on. Its like IE mode isn't honoring that setting. 

For fun, I changed Compatibility Mode to IE8. In that mode, the message appears, however when I go to view basket where I would import updates, I get a different error, "Error number: 800A138F" instead.

I am doing this on a W11 system with WSUS and other RSAT tools installed.
