OperatingSystemName                         Idx Version        PublishedDate        IsoPath
-------------------                         --- -------        -------------        -------
Windows Server 2012 R2 Standard (Server Core Installation)   1   6.3.9600.17031 3/18/2014 1:29:36 PM E:\LabS
Windows Server 2012 R2 Standard (Server with a GUI)       2   6.3.9600.17031 3/18/2014 1:37:34 PM E:\LabS

If you want to update the non-code datacenter image, the index would be 4 and the command looks like this:

Update-LabIsoImage -SourceIsoImagePath $labSources\ISOs\en_windows_server_2012_r2_with_update_x64_dvd_4065220.iso `
-TargetIsoImagePath $labSources\ISOs\UpdatedServer2012R2.iso `
-UpdateFolderPath $labSources\OSUpdates\2012R2 `
-SourceImageIndex 4

The script below does is all automatically. It looks for the latest ISO that provides “Windows Server 2012 R2 Datacenter (Server with a GUI)” and uses the correct index.
