Microsoft allowed people who pre-ordered the Xbox One version Quantum Break to get the Windows 10 version for free in the Windows Store. However, you still need to sign into your Microsoft Account to play that version of Remedy's temporal-based action game. If you don't, the game's player character Jack Joyce gets an interesting makeover.
As spotted by Reddit user disastorm (Via Gamespot), Joyce will sport an eye patch if Quantum Break on Windows 10 is not used on a authorized Microsoft Account. This was done as a fun anti-piracy measure, according to Remedy's official Windows 10 FAQ on the game:
DRM might've accidentally triggered. Make sure you've logged into your Microsoft account before starting the game.
If you didn't get the Windows 10 version of Quantum Break for free, you can still buy it in the Windows Store for $59.99.
