Over at my personal Blog I provide a powershell example of how users can migrate their personal TFS Work Item queries from one project to another. This is useful when migrating from a TFS 2010 server to a new TFS 2012 server. http://www.mikepoulson.com/2013/08/migrating-tfs-2010-or-2012-personal.html
Over at my personal blog (www.mikepoulson.com) I have a post on using Differencing Disks with an SCVMM template. The main issue I ran into when first doing Diff disks with VMM was making sure the Parent VHD was on the target HyperV host. The PowerShell script at http://www.mikepoulson.com/2011/07/how-to-create-differencing-disk-vm-from.html does that work for you.
