Microsoft has officially released the Windows 10 as an update to Windows 7/8/8.1 users worldwide only two days ago.
In these two days, Windows 10 has already been installed more than 14 million times, its maker has revealed. And this was achieved in just the first 24 hours of availability. That's no small feat for such an incredibly short period of time.
Obviously, the great distribution was also helped tremendously by the fact that Microsoft is giving away the update to Windows 10 for free for those who have Windows 7 or Windows 8.1.
