windows - Disable restart after update prompt for server 2008 R2

I run server 2008 r2 as my desktop OS.

I am trying to disable the annoying restart prompt that comes up after installing updates. The most I can postpone it to is 4 hours.

I have tried disabling “Re-prompt for restart with scheduled installations” and enabling “No auto-restart [...] for scheduled Automatic Update installation” in Computer Policy -> Computer Configuration -> Administrative Templates -> Windows Components -> Windows Update in gpedit.msc, to no avail.

I have looked at various guides, and nothing seems to work.

I do want automatic updates, and I have it set to notify me immediately, and allow me to choose what to download and install. I just don't want this nagger screen to keep coming up, for various reasons.

Is there a fix?

Please don't respond with a lecture about why I should restart automatically, as your assumptions may not be valid.

Answer

From Disable Windows Update restart nag:

To stop this service, open Command
Prompt (Start>Run>cmd>Enter) and type
the following command sc stop wuauserv. This will not prevent
Automatic Updates from starting at the
next boot. So don't worry, you'll keep
getting Windows updates. Just don't
forget to restart eventually.

From disable Automatic Update restart prompts using Windows Computer Policy
(was this the one you mentioned in your post?):

Start / Run / gpedit.msc / Local Computer Policy / Computer Configuration / Administrative Templates / Windows Components / Windows Update / and disable Re-prompt for restart with scheduled installations.

You can use a freeware product to Disable Windows Update Restart Alert Message With WindowsUpdateSilencer:

If you want to get rid of Windows
Update notification then here is
WindowsUpdateSilencer useful tool
which runs in the background and will
automatically silence all Windows
update notifications.

(I have never used this program and can't vouch for it, especially on Server 2008.)
