Games running on outdated disc-based DRM won't work in Windows 10, according to Microsoft's Boris Schneider-Johne.

In an interview at Gamescom, Schneider-Johne told Rocket Beans (translated by Rock Paper Shotgun), "this DRM stuff is also deeply embedded in your system, and that’s where Windows 10 says, 'Sorry, we cannot allow that, because that would be a possible loophole for computer viruses.'"

"That’s why there are a couple of games from 2003-2008 with Securom, etc. that simply don’t run without a no-CD patch or some such."

Though certainly a boon for system security, given the patchy history of Safedisc and SecuROM, it calls into question whether games like BioShock and Mass Effect will be able to run from their discs.

Downloadable versions of the titles affected should run fine.

If accurate, the claim is ironic, as legitimate software will now no longer function thanks to anti-piracy measures, and unfortunate, as it continues the gaming industry's history of rendering older games unplayable.

The report follows an updated Services Agreement from Microsoft that allows the company to remotely disable pirated versions of its first-party games.

"We may automatically check your version of the software and download software updates or configuration changes, including those that prevent you from accessing the Services, playing counterfeit games, or using unauthorized hardware peripheral devices," reads Section 7b of the agreement.

The agreement covers Windows, Skype, Office, Xbox Live, Bing, Cortana, and more, and states that Microsoft can add or remove features or cut off third-party apps at any time.

Windows 10 is out now, if you're prepared for it.
