Today's the day: October 17th, the day Microsoft starts rolling out
Windows 8.1. And right now, the minute this post first went live, is
7AM ET, the exact minute the OS update will start appearing in the
Windows Store as a free download. Don't have a Windows 8 device? You can
still install
8.1 on a Win 7 machine; you just won't get the update for free. For
folks using Windows 7, you'll pay the same price...
