From this post I'm going to start a new series of posts in my blog. My intention is to spot some of non-obvios similarities and differences in this two OS. From a Linux user perspective of course.
Recently I've noticed that starting from Windows 7 this OS got the 'whoami' command which was taken from UNIX/Linux after about 20 or 30 years.
Not to mention 'Run as' option in Windows XP which was obviosly taken from the UNIX/Linux sudo example. At least a decade or two later I think.
