Block all windows update servers?
(sh.itjust.works)
Community for discussing enterprise networks and the ensuing chaos that comes after inheriting or building one.
Use Group Policy to disable updates.
If you have a Home version, disable the Windows Update service and the Windows Update Health service which prevents the Windows Update Service from being disabled.
Hkey_local_machine\system\CurrentControlSet\Services\WaaSMedicSvc
Change the Start value to 4 (disabled).
Now you can disable the Windows Update Service.
