You may have seen the "Smoked by Windows Phone" ad campaign, where a Windows Phone does something faster than another phone. Well how about "Smoked by Hyper-V Server" challenge?
As part of my initiative to "Do IT the Microsoft way", I set about switching over from VMware ESXi to Hyper-V. After installing Hyper-V Server 8 Beta, I noticed it seemed to boot a lot faster. This gave me the idea to have my own little "Smoked by Hyper-V Server" challenge.
I finally had some time to install the Windows Server 8 Beta in my lab. Since doing so, I've discovered there are 4 faces to Windows Server 8. During install, you're presented with a choice between 2 of them, "Server Core" and "Server with GUI". The other 2 currently require running a few commands to get to them. The best part is, you can switch back and forth between then anytime you want.
