Sources close to the top have confirmed that Windows 8.1 has released to manufacturing (RTM) and is on the way. The rumor, which is now fact, was leaked last Friday (perhaps to defer attention on the retirement announcement concerning Steve Ballmer). Like many readers, I’ve been running the Windows 8.1 Preview on a few machines for the past few months. I even have my sons and wife playing around with it on the family PC in the TV room. The consensus: We like it!
