Since the time I got the new thinkpad I was fustrated that I have to press two keys ('Ctrl-Esc') to simulate the Windows Key, Then I found how to remap any key of my choice at this site http://www.hanselman.com/blog/GryoscopesAndRemappingAWindowsButtonForTheIBMThinkPad.aspx 

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout]
"Scancode Map"=hex:00,00,00,00,00,00,00,00,02,00,00,00,5B,E0,38,E0,00,00,00,00

to make the Right-Alt as the Windows Key.
