How to disable WSUS auto-restart after windows updates are installed?

By IT Generalist ·
Is there a way to disable auto-restart after scheduled updates are installed, weather user is logged on or not. There is an option to disable auto-restart when a user is logged on in the Windows Update Group Policy but no option for when user is not logged on. I would like to be able to restart servers in a more controlled manner rather than having them restarted automatically in the middle of the day.

Thanks.

How To Disable Reboot After Windows Automatic Update

Running any version of XP prior to Service Pack 2? Back up your registry, then add or change this key:
HKEY_LOCAL_MACHINE\ Software\ Policies\ Microsoft\ Windows\ WindowsUpdate\AU
If it doesn?t already exist, create the DWord value ?NoAutoRebootWithLoggedOnUsers?. Set it to 0 if you want Windows to automatically restart, or 1 to prevent automatic restart. Then exit and reboot your computer. The result: As long as users are logged on the system, it won?t take matters into its own hands.
Post-XP SP2, one user reports success at disabling automatic restarting after updates on XP Home by:
1.Disabling Windows Automatic Updates;
2.Opening Task Manager (by pressing Ctrl-Alt-Del);
3.Ending all instances of wuauclt.exe, then;
4.Making the registry changes noted above.
Once Service Pack 2 is installed, XP Pro, 2000 and 2003 users can stop automatic reboots by editing Group Policy. Start the Group Policy editor, select Windows Update in the Windows Components portion of the Administrative Template, and choose No auto-restart for scheduled Automatic Updates installations. You can also completely disable Windows Update at the Group Policy or User level.
Beyond that, Microsoft provides exhaustive instructions for managing Windows Updates on networks. Its old program, Software Update Services (SUS) was replaced as of 6 December 2006 by WSUS (Windows Server Update Services). Adding a letter to the acronym gave SUS more oomph, don?t you think?
If you haven?t yet upgraded from SUS you have some prep work ahead. Before installing WSUS server, make sure you?ve downloaded BITS (Background Intelligent Transfer Services 2.0) for Windows 2000 or Windows Server 2003. BITS does a P2P-like thing, downloading updates in the background and sucking up all the network bandwidth it can get. Also, at a minimum, you?ll need MSDE 2000a for Windows 2000, WMSDE for Windows Server 2003, or SQL Server 2000 with SP3. WMSDE comes in the WSUS download. Microsoft has step-by-step guides for deploying, migrating to and running WSUS.
And if, after all these gyrations, it still doesn?t work, remember: Just because it?s Microsoft?s product, doesn?t mean they have to take responsibility for it. As so many of our contributors like to say, ?Read your EULA.?

Please post back if you have any more problems or questions.

One thing the policy can not do:

by sertac73 In reply to How to disable WSUS auto- ...

I use the policy "No auto-start with logged on users for scheduled automatic updates installations".
This policy really prevents that the server to reboot itself if a user is logged on.
But as soon as the user is logged off, the server begins to reboot itself. That is what is not desired but cannot be prevented.

Its hard to believe that microsoft considers that any server where no users are logged on can be restarted anytime.

I hope I'm wrong with this and there is a method to prevent a server to reboot itself after its patch intallation and where no users are logged on.
