NT Authority \System disable Winupdates

Hi all,

We experienced in the last weeks that win updates have been installed without user input on our critical systems. We already set GPO's that Winupdates are only allowed to be installed with user input and not outside of working hours. We set those to 12am - 12 pm, just in case.

Those systems receive their updates once every month via WSUS. It can happen that the updates are downloaded but wont be installed for 2-3 weeks
After some investigation have we found out that the NT Authority \System account is forcing the installation of those restarts. Is it possible to prevent this system account to install the updates on its own?

The systems are running on LTSB and LTSC versions

Thanks for your posting on Q&A.

To avoid misunderstanding, please help to confirm which GPOs the computers have applied first.

In addition, what's the OS version of the computer? In my opinion, the computers will try to install updates out of active hours. Please provide the below registry values for reference if it is convenient for you.
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU

Regards,
Rita
