Quantum Break is currently confirmed for Windows 10 and there is no information on a Steam version yet. Head of PR at Remedy Entertainment, Thomas Puha confirmed that they will share more details about the Windows 10 PC version in February.

@Tovarisc_ no comment, sorry. We'll talk more about W10 version end of February. — Thomas Puha (@RiotRMD) February 11, 2016

He talks more about the demo that the press had to play today and also assures PC users that Remedy will try their best to make the PC version great.

I would like to point out that we really gave the press hours on the game. Not like we gave a 20 min sequence. It was good 90-120 min demo — Thomas Puha (@RiotRMD) February 11, 2016

The cinematics team was in tears as the build had screen tear problems and the press was playing it. We tried to fix but ran out of time — Thomas Puha (@RiotRMD) February 11, 2016

@Tovarisc_ lol, good to clarify. Look, Remedy knows its gotta make the PC version great and we are working hard to make it happen. — Thomas Puha (@RiotRMD) February 11, 2016
