So I can't claim my (actually legit) Windows ME is pirated & get a "free" Windows 10 ?
Both articles start out with :
users with a pirated version of Windows are also eligible for the free update of the operating system
millions of users of illegal versions of Windows
offering free upgrades to Windows 10 to all Windows users, regardless of whether they are running genuine copies of the software.
Then further down in the Reuters article the first qualifier:
Terry Myerson, who runs Microsoft's operating systems unit, announced the plan at the WinHEC technology conference in Shenzhen, China.
We are upgrading all qualified PCs, genuine and non-genuine, to Windows 10," he said in a telephone interview with Reuters
Then the zdnet shows this is for Windows 7 & later.
