|Try disabling the 'service' that's required for automatic updates |
to work - Windows shouldn't be able to override that:
This is a workaround rather than a fix, but it should have the desired effect:
Start >> Run
Type services.msc and press Enter
Find 'Automatic Updates' in the list and double-click it.
Click the 'Stop' button if it's not greyed out.
If it's greyed out, just ignore that step.
Set 'Startup type' to Disabled
If you decide you want to have AU turned on at a later date you'll
need to reset the service back to 'Automatic' using the same
method as above.
