I was a systems engineer supporting Windows and software running on Windows at a large corporation for a decade. My only complaint at the time was that the CLI was so inferior to Unix/Linux.

MS' increasingly poor UI/UX decisions starting with Windows 8/Server 2012 have caused me to relegate Windows to a "legacy support" role in a VM on any new hardware I buy. They really had to work to overcome all of that good will, but they've been relentless.
