Released in 2007, I believe.
@JulieSqveakaroo duckduckgo says released to manufacturers in july 2009
@JulieSqveakaroo the only thing I can guess is that they consider windows 3.x to be "the first one" and they ignored NT Workstation entirely because who the hell even knew that one existed
or maybe they ignore ME/2000 instead because they want to pretend that never happened
