MICROSOFT HAS CONFIRMED that being a Windows 10 Insider does not guarantee a free copy of the operating system.
The company is using the Windows Insider programme as its biggest ever beta test for what is being billed as the final or definitive version of Windows, or Windows-as-a-service.
But Microsoft has made it clear that its generosity stretches only so far, and that being a beta tester is an honour in itself.
Windows 10 will be offered as a free upgrade to Windows 7 and Windows 8.1 users when it launches later this year.
Windows 8 has reached end of life, and customers will need to take the free upgrade to Windows 8.1 first, which is still subject to holdouts totalling 5.88 percent of the OS market, according to this month's Netmarketshare figures.
