One story that circulated a couple of days ago claimed that Microsoft would be giving pirates of their operating system a free upgrade to Windows 10. The news seemed a little strange at the time, considering Microsoft's previous stance on piracy, so it's not hugely surprising to discover that it was
too good to be true.
Microsoft has clarified that people who are running a pirated copy of Windows will be able to upgrade to Windows 10 relatively easily. However, their Windows license will remain invalid after the upgrade process is complete, meaning they won't really be getting a "free" upgrade to Windows 10.
