At least I decided my self I should try Core Edition of Windows …….
Decided to install Windows Update service to new Windows 2012 Core edition.
Struggle is I have to get myself familiar with all PowerShell commands, which is challenging but that’s the only way you will learn it.
So we are going ahead with Core edition, good luck to me ….
We can install WSUS using Windows internal Database by below command (-Whatif simulates the result without actually running the command).
Install-WindowsFeature -Name UpdateServices -IncludeManagementTools -whatif
But we faced an issue with installation, after 92% installation fails with pending restart request.
We figured out it’s a permission issue with logon as Service.
The solution is to modify your Logon as Security rights from Local policy or from GPO.
How to do from GPO
In the Computer Configuration –> Policies –> Windows Settings –> Security Settings –> Local Policies –> User Rights Assignment branch, edit the Log on as a service setting, and add the following accounts: IIS_WPG, NETWORK, NETWORK SERVICE, SERVICE.
There is a detailed blog on installation here —http://blogs.technet.com/b/heyscriptingguy/archive/2013/04/15/installing-wsus-on-windows-server-2012.aspx
