Out with the old, and in with the new. Microsoft yesterday stopped providing Windows 7 Professional and Windows 8.1 licenses to original equipment manufacturers (OEMs), including its PC partners and systems builders. This means that, as of today, the only way you can buy a computer running Windows 7 or Windows 8.1 is if you can still find one in stock.
Driving people like me to the Embedded channel. Many still buy computers with Windows OS and one of the snafus with Windows 10 for consumers is that automatic updates are mandatory.
