It's still Windows and still a 'one horse race' computing monopoly for the average home clicker to roll with
so they're not losing money
giving it away 'loaning' it for free, as they get a good cut from apps running on it
a few bucks from hardware manufacturers and OEMs etc
and they won't do anything seriously silly to be out of a paycheck
For me Win 10 is just a re-skinned Win 7, 8, 8.1 OS that wants to play guard dog come boss
I'd rather fire up a COA OEM licensed XP or Vista box or Linux, rather than Win 10 or a Mac money pit
I could care less if XP. Vista or 7 are 'unsupported',
they work, run all apps and fast, and malware free,
what's the 'support' or lack of it going to do for a reasonably informed user ?
