Earlier today we heard that Microsoft will be making Windows 10 available as a free upgrade to Windows 7 and Windows 8.1 users.
Now it would appear that this free upgrade will not just be available to people who have purchased Windows in the past, Microsoft will also allow pirated copies of their software to receive the free upgrade.
Microsoft are obviously looking to stop piracy of their Windows platform and by offering users who are running pirated versions of their software a free upgrade to the legitimate version, this may help them reduce Windows Piracy.
Microsoft will make money from Windows 10 by selling other software to users, like subscriptions to their Office software and other software.
The new Windows 10 platform is launching this summer and Microsoft is looking to unify the user experience across PCs, notebooks, smartphones and tablets.
