Windows 10 installed on 75 million devices after just a month of availability

The free upgrade from Windows 7 and 8 to Windows 10 is doing wonders: In just under a month of general availability, Windows 10 is now running on 75 million devices.

Unsurprisingly, Windows 10 appears to be doing better than Windows 8: Back in 2012, only 40 million Windows 8 licences had been sold in the first month. After six months, Windows 8 had risen to 100 million licences sold—and "sold" is likely to be a very different figure from how many devices were actually running Windows 8. So, 75 million devices running Windows 10 after a month is pretty darn good.

The 75 million figure comes directly from Yusuf Mehdi, a marketing chief at Microsoft. Mehdi also shared a few other semi-interesting Windows 10 tidbits: 90,000 different PC and tablet models have upgraded to Windows 10; Windows 10 has a presence in 192 countries (I wonder which one of the 193 UN member states is missing?); the Windows 10 Store has seen six times more downloads per device than Windows 8; and, most importantly, Cortana has told over half a million jokes.
