They even did this silly "corner thing" in the server edition, Windows Server 2012 - I remember the first time I RDP'd onto one, and had
no clue how to open the start menu (the Windows key didn't work over RDP)!
I had to google it, obviously whilst cursing profusely the whole time. Microsoft have a lot of UI/UX people - it boggles the mind that someone thought this was a good idea!
