Firstly there are the software losses. Most of these will only affect a small number of users, but upgrading will mean saying goodbye to Windows Media Center, the card game Hearts, and Windows 7's desktop gadgets. Anyone in the habit of using floppy disks on Windows will also have to install new drivers, and Microsoft warns that watching DVDs will also require "separate playback software." Microsoft manager Gabriel Aul has said on Twitter that a DVD option for Windows 10 is coming "later this year," but early upgraders can always download VLC instead.
n addition to the software losses, there are also a number of limitations for some of Windows 10's most exciting features. Cortana will only be available in the US, UK, China, France, Italy, Germany, and Spain at launch, while Windows Hello (which offers support for various biometric passwords) will need an infrared camera for facial recognition, or a supported fingerprint reader. The Xbox Music and Xbox Video streaming apps will also be constrained by the usual, complex web of region-based licenses.
As for Cortana, what happened to Canada?
