I'm trying to automate WSUS with powershell, however to do this I need to know what version is installed. How do I find this information?

You can use the following code to get the version of WSUS in PowerShell:

[void][reflection.assembly]::LoadWithPartialName("Microsoft.UpdateServices.Administration")
$wsus = [Microsoft.UpdateServices.Administration.AdminProxy]::getUpdateServer(“dc1”,$False)
$wsus.Version

Or you can use PowerShell:

get-itemproperty -Path 'HKLM:\SOFTWARE\Microsoft\Update Services\Server\Setup\' -Name IISPreviousInstallRevision

WSUS was initially a separate software which you had to download and install, but since Windows Server 2008 R2 it has been included in the OS.

Windows Server 2012 R2 runs WSUS 4.0.
