www pcworld com/article/2873214/windows-10-will-be-a-free-upgrade-for-windows-7-and-8-users.html Kicking off the consumer-focused Windows 10 event in Redmond on Tuesday, January 21, Microsoft operating system chief Terry Myerson announced that current users of Windows 7, Windows 8.1, and Windows Phone 8.1 will be able to upgrade to the new operating system for free as long as they do so within one year of Windows 10's launch—even if your version of Windows is pirated. Once you’ve claimed the upgrade, it's permanent, and Microsoft will keep you updated for the supported lifetime of the device. So all you need to do is install Windows 10 within one year and it'll be free even if you have a pirated version? Seems too good to be true. I dont think this writer has his facts correct. I read somewhere that the activation is only for one year.
