I would consider 'Windows 9'
if Micro-shaft would evar create it. It'd have to be 7-like in appearance and everything else (i.e. 3D Skeuomorphic, no spyware, no adware, no 'app store', no cloudy logon, NO FORCED UPDATES), with the updated kernel etc similar to 10.
But please no "you must have micro-shaft sign the kernel drivers" requirement. that's just wrong...
(yeah fat chance Micro-shaft would CARE ABOUT CUSTOMERS enough to DO that)
