I got a W2k8 R2 key (why did I only get one?) from Dreamspark using method from this forum. Thanks! I used it to activate Installation on physical machine that I installed Hyper-V role on. As a Hyper guest I have installed W2k8 R2, but unfortunately the Dreamspark key is now used up and the ability to get keys from Dreamspark is gone. I was also planning on installing a Windows 7 as a Hyper-v guest. Is there any way to use the bios mod and oem keys activation method discussed here to Activate my Hyper-v Guests? Or what other options are there? PS. If my options are slim I would of course greatly appreciate a W2k8 R2 key as a gift if there is someone here with one to many
