If you have a pirated copy of Windows 7 or 8 and you decide to take Microsoft up on the free offer to upgrade to Windows 10, you'll be gently reminded with a watermark on your desktop that this is not a genuine copy. Of course you'll be able to install the OS and receive updates (at first), but nothing is completely free. There still is no word as to what it will cost users that have to shell out money for a license, but hopefully Microsoft takes the Apple approach and makes it affordable for everyone.
The announcement comes after Myerson confused the tech world a few months ago by declaring that pirated versions of Windows could partake in Microsoft's free upgrade offer for Windows 10. It turns out that's not exactly true: The company later said that non-genuine installations would have to go through the Windows Store to upgrade to Windows 10, which was a strong hint that it would make pirates pay.
