Here are some step by step notes I have taken to create a template VM. Step A is not necessary for the group to work, but it is a best practice.  I would suggest creating a very basic template and creating a group from that basic template. Once you feel comfortable that your group is working properly, try adding more features and software and re-provisioning the group using the updated template. 
I have Windows 2012R2 with hyper-v installed. I have installed the v_workspace in cloud mode for hyper-v following the video. I am trying to create a Windows 2012R2 Template for use as the VDI master. Can someone point me to an article or video. I have watched the videos that are available under v_workspace, but they reference an earlier video that I cannot find. Does any one have any clear-cut instructions?   Thanks in advance
