I’ve been doing some recent experimentation with nesting Microsoft Windows 2012 HyperV under vSphere5.1 – and that lead me to looking at the UDA as way of pushing out a scripted installation of Windows 2012. I had a quick word with Carl Thijssen and he very kindly put together a patch bundle to add support for Windows 2008, Windows 7/8 and Windows 2012.
If you run the UDA or intend to I’d highly recommend this patch. Although you might want to backup or snapshot your UDA first, just in case something goes astray during the upgrade itself. Pop along to the download page here or on ultimatedeployment.org/download.html to grab the new patch.
