Registry Tweak to Disable MS Communication?

I found that this registry edit will disable all communications (AFAIK) to Microsoft. It does need further investigation though. When run the internet icon in the tray shows disconnected, but internet access is fine except for all things Microsoft. With the new 20H1 build it can be turned off and on by substituting in a 1 or a 0 then restarting.

Block MS

Code:

reg add "HKLM\SYSTEM\CurrentControlSet\Services\NlaSvc\Parameters\Internet" /v "EnableActiveProbing" /t REG_DWORD /d "0" /f

Allow MS

Code:

reg add "HKLM\SYSTEM\CurrentControlSet\Services\NlaSvc\Parameters\Internet" /v "EnableActiveProbing" /t REG_DWORD /d "1" /f

I would appreciate further investigation into this matter, along with comments.

 

Thanks bud!
