Prevent windows update forced reboot

[Guest Matthew Bilsky]

I have it set in my group policy that computers should run automatic update

every evening, and should install all updates available. Then it should not

reboot the computer, nor ask the user to restart.

 

Saturday night, all of my computers, including my servers restarted

automatically, and then displayed that annoying green shield in the task bar

telling me that microsoft had updated my computer.

 

I want to prevent this from happening again.

 

Someone suggested using wsus, which i have installed, but haven't

implemented yet, but i would not like to have to approve every update, and

sort out which ones will restart the computers.

 

how can i fix this?

 

thanks.
