Hello Ramesh,
This time I thought we were (almost) there....
I ran the PowerShell command (no acknowledgement from PS on the result?? - weird).

Reboot and reinstalled Windows Web Exp. Pack from your link. For the first time I could observe the installation process worked. Installed and checked dependencies. I was sure we hit Jackpot....
After another reboot I activated Widgets in Taskbar Settings, waited a moment and launched the Widget Board.
Disappointed - but no improvements or changes. One thing. The "One or more Dependencies needs to be download and installed" Msg Box does not show up anymore. I noticed that a couple of "Troubleshooting scenarios" ago. What made the change I don't know, as so much has been done on this annoying issue.
Anyway, the "Feed" Icon to the upper left is still missing and no MS Feeds available. Note:

I hope you do not give up on this, Ramesh.
Best,
Anders
