I was reading some older posts and horror stories of things accidental Windows Updates can do like change the registry of windows defender or update the graphics cards to a version that they shouldn't be, etc.. These are the things I am looking into. If you can think of anything else to look into, please let me know.
You can try to disable Windows Update in "
Search->Edit Group Policy"
Under 'Computer Configuration', expand "
Administrative Templates->Windows Components->Windows Update".
On the right pane, set 'Configure Automatic Updates' from 'Not configured' to "
Disabled".
Using that setting, my Windows10 Rig has been at version 1709 for 5months and never updated.
I don't know if will actually work since I've deferred windows updates in the settings for 365days.
But this is what the description says:
Some features are still being automatically updated though.
And to disable automatic drivers update, enable the policy: "
Do not include drivers with Windows Updates", as written in its description.
You might want to check the other policies in there too.
