While Windows 10 is largely good news for gamers, it turns out that those with a collection of older games laden with DRM copy protection software are going to have a hard time getting them up and running on the new OS. In an interview with Rocket Beans TV (as translated by Rock, Paper, Shotgun) at this year's Gamescom, Microsoft's Boris Schneider-Johne explained that that Windows 10 won't be able to run games that use SafeDisc and SecuROM technology.
"Everything that ran in Windows 7 should also run in Windows 10," said Johne, "There are just two silly exceptions: antivirus software, and stuff that’s deeply embedded into the system needs updating—but the developers are on it already—and then there are old games on CD-ROM that have DRM. 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."
Great news. Don't think modern games really have to worry about this, but it's a good preventative measure. Glad to see that SecurROM is all but dead now.
