Is it possible to block Windows 10 Update servers on a firewall by IP, name, and port? Looking to use Windows 10 Pro in a work environment without having it update? If this is possible, what are your thoughts on any affects this may cause to Windows 10 Pro. Do you think disconnecting they system from MS will cause it to unauthenticated the license or cause other issues. We are currently testing this too, will update if we have success.

Yes Indeed. I did it the manual way in many locations.

If I recall, this was the minimum, there may be more.

Computer>right-click>manage

Scheduled Tasks>Microsoft>Windows Updates> delete all or disable

(also,delete all,Telemetry) <

Group Policy Editor. run as administrator gpedit.msc look for updates and disable all users except ?

win+X >Services

  • disable Windows Updates
  • Control Panel > Windows Updates
    • disable

This also,affects Metro live updates, (news weather sports) which may fill Event Logs with errors under Windows Apps...

To verify after... Get/run Procmon.exe and trace only process name = wupdt.exe or wuauclt.exe
