Although, there is some truth in that, the software maker is now stating that pirated versions of Windows can still upgrade to Windows 10 free, but they will not get a genuine license in the process. So, the non-genuine copies of Windows will stay non-genuine after upgrading to Windows 10. Furthermore, Microsoft will not support versions of the operating system that are not properly licensed. The company also confirms that the plan to allow free upgrades for pirated copies of Windows is not limited to China, which means that it applies to all markets. A statement from the company reads: This explanation actually makes more sense, because what would stop anyone from building a custom PC with a non-genuine version of the operating system to then upgrade for free to Windows 10. This would be a backdoor that millions of people would use to get a free copy of Windows. Microsoft plans to launch Windows 10 later this summer, which here in the United States ends on September 21. Now the company have roughly six months to finish and roll out its operating system for free to millions of PCs running genuine copies of Windows 7 and Windows 8.1. It sounds like a mission impossible task, seeing that there still a lot of missing features, including Project Spartan, Windows Hello and Microsoft Passport biometric framework.
