And so, for the first time in Microsoft’s history, Windows is now free, at least for the next year. Anyone can go to http://www.microsoft.com/windows/windows-7/download.aspx and download the software for installation onto any PC, including Intel Macs. They can use it until March 2010, at which point it will begin nagging for payment by shutting down every two hours. This is similar to how heroin is sold.
