Windows Server 2016 RDSH - Start Menu stops working

On our farm of Windows Server 2016 RDSH (Remote Desktop Session Host) I've had seemingly random issues with the start menu stopping working.  This likely correlates with a Windows update being applied, but it's hard to tell as you do not always know immediately that it's stopped working (users complain days later or never complain and you notice when doing other maintenance, etc).

Searching the internet you find a number of solutions, but the most crazy (in my opinion) solution I found was the one that actually worked! 

In this post user MrManual says to delete and recreate a registry key dealing with the Firewall.  One, like me, would think this crazy and continue on trying all the other solutions only to have the issue remain (or return shortly).

Finally, figuring it's best to try a crazy solution than rebuild the server I open powershell and give it a go:

Remove-Item "HKLM:\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\RestrictedServices\Configurable\System" New-Item "HKLM:\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\RestrictedServices\Configurable\System"

Click start menu and GASP it opens!

Note: other ideas on the thread do work, but seemingly only temporary.  I still suspect this to have something to do with the crappy UPD's.
On the note of UPD's one might ask "if you hate UPD's so much why not switch to fxlogic?  I mean, it is free afterall..."

Dell Latitude 7480 / 7490 loud fan issue

We have a lot of Dell Latitude 7480 / 7490 laptops deployed.  When I first got them in we had lots of issues and complaints about the loud fan speed.  Under load this is understandable, but many times this would be with no load.   This is a common issue early on for these models as one can see from the numerous posts online:

In the past when I would get one of these laptops it was a matter of ensuring the BIOS was up to date and the issue would be gone.  Lately, my own laptop (7490) started having high pitch fast fan noise.  Of course I remembered right away that I had recently updated the BIOS to 1.13.1.
I quickly decided to do a BIOS downgrade to 1.11.0 to see if that would help.

No more loud fan noise at this point... Having issues with your fan always running top speed? Try an older BIOS version and call Dell rep to complain.
