We decided at W7V with Fibonacci and Secr9tos to create a $OEM$ folder that will install all necessary packs to get Windows Server 2008 R2 to a Workstation OS.
Till now the only way to do this was either to "sysprep" the release or use RT Server Customization Tool from Ben, involving lots of manipulations and maybe some errors if you are not acquainted with Windows Imaging and Deployment Techniques.
After lots of testing (almost 80 VM tests on all R2 Editions in 1 month) the $OEM$ Folder was ready.
I integrated "this folder" to all editions (Foundation, Standard, Enterprise, Datacenter and Web Server) in the same install.wim file
