WSUS problems

Hi Experts,

I have WSUS running.
But always when I approve some updates I get problems with some servers.
My WSUS policy is just to approve updates and download to the servers and I decide to install them.
But for some reason some updates installed automatically.
And this stopps sometimes some services like SMTP or EXCHANGE.

How to sort out this problem ?

How have you set up the WSUS, have you set it up to use Group Policy?  If so have you configured the appropriate Group Policy Settings that define when updates are installed, or have you just configured the server locations?

By default, if these settings haven't been set it will auto download, install and then reboot.

The only way they would install automatically on a server is if that server is configured to install updates automatically.  It's best to control these settings through the use of Group Policy.  If this is what you're doing, make sure the servers in question are getting the correct GPOs applied.  You may want to provide a screenshot of the Windows Updates settings screen, so that we can verify.

Yes I installed WSUS in combination with the GPO's
And the GPO's are configured.
But when I approve updates to servers, some of them are installing automatically or just some parts.
I can see it after approving it.
How is this possible ?
What GPO Settings have you set?

Can you detail them/Screenshot them so we could assist?

we discussed some things in our company.
Because we have not so many servers, we want to get rid of WSUS.

How to uninstall WSUS or deactivate it ?
And how to tell each machine, to inform if new updates available ?

The only thing telling other computers about the existence of WSUS are the Group Policy settings (the specific one is "Specify intranet Microsoft update service location").  So if you don't have those, then they will check with the Microsoft update servers for updates.  To keep the settings that define how Automatic Updates are configured, (i.e. download automatically and notify to install, or automatically download them and install, etc.) so that users don't/can't disable updating completely, look for the "Configure Automatic Updates" setting.
