Microsoft initially announced Quantum Break as an Xbox One exclusive. They later surprised everyone when they announced it was coming to PC on the same release date as the Xbox One version. However, the company also stated that Quantum Break will be a Windows Store exclusive, thus a Windows 10 exclusive.

As of the announcement on August 10, 2016, this has changed and Quantum Break will be releasing on Steam on September 14, 2016 with support for Windows 7 and above.

All customers who succumbed and wound up buying the Windows Store version, under the impression there was no other choice, are left with a poorly optimized version of the game that is riddled with bugs predominantly related to the Windows Store version and the limitations of the Universal Windows Platform (UWP).

Considering this radical change in Microsoft and Remedy's approach to marketing the game, everyone who bought Quantum Break on the Windows Store ought to receive a free key to redeem the game on Steam; granting them greater options to play the game on the platform of their choice.
