add update remote vs local early exit check

there seems to be a windows gsm remote vs local version check, but even if the versions are different it seems to still run the update. Should add a check within the update fn directly that exits and doesnt actually update when the versions are the same

Start by locating the update function and the existing WindowsGSM remote-versus-local version check. Verify how equal versions are handled, then confirm that the update exits without changing anything when the versions match.
