Preparing WSUS for Windows 8 and Server 2012

Now that Windows 8 and Server 2012 are RTM and available to download from the usual places (VLSC, TechNet, MSDN, Intune etc) various other Microsoft solutions are getting updates to prepare them to support the Operating Systems.

Yesterday it was Windows Server Update Services (WSUS) turn and a hotfix to add support for Win8 and Server 2012 was released in the form of KB2734608.

You can read the knowledgebase article here:

This also appears to be a bit of a rollup update with it also including/replacing the following updates:

• 2530678 System Center Update Publisher does not publish customized updates to a computer if WSUS 3.0 SP2 and the .NET Framework 4 are installed
• 2530709 "Metadata only" updates cannot be expired or revised in WSUS 3.0 SP2
• 2720211 An update for Windows Server Update Services 3.0 Service Pack 2 is available

 One thing to take note of is this section in the known issues about existing clients:

If you have Windows 8 or Windows Server 2012 clients that synchronised with WSUS 3.0 SP2 before you applied this update, wait for the update to be applied to the WSUS servers, and then follow these steps:

On the affected client, open cmd.exe in elevated mode Type the following commands.

Net stop wuauserv
rd /s %windir%\softwaredistribution\
Net start wuauserv

Chances are that you haven't got too many Windows 8 or Server 2012 clients deployed yet in production, but if you have then this seems like something to get scripted, packaged and deployed via Configuration Manager... oh wait, you'd need System Center SP1 for that to be supported in production... time to break out PowerShell 3 instead ;)
