Problem:The problem is evident. It's crazy how Microsoft forced its metro-style UI to Servers. (Similar to the fact that msn-s website is default in IE for server OS-es up until 2008 R2. Who would read msn news on a server??) Regarding the Metro style, if you're working through a windowed Remote Desktop Connection, it's a pain in the foot to restart the machine for example. First, you have to hover on the left corner, click then hover on the right corner for the power icon to appear. Very frustrating.
Solution:I found a very-very great app for this which will bring back the good old start menu for Windows 8 and Windows Server 2012. Get it from http://www.classicshell.net/.
Big thanks for creating the app and making it open source & free!
