Microsoft has released a new update for Windows Vista, Windows 7 and Windows 8 computers that might break some old games that you have installed on your hard drive or SSD. Basically the update disables SafeDisc, which is a DRM that protects software on optical disks, including games. When this happens you will not be able to run your old games, which use, you guessed it – SafeDisc.
Microsoft says this is done for your protection and that software, which relies on SecuROM DRM, is not affected. There’s some good news in this, though – Microsoft has published a rather lengthy manual that describes how you can run your SafeDisc games with the update installed but you will have to mess with your Windows registry, which is not that safe, to say the least. Unfortunately there’s no information on how this update is called so if you install updates read what the descriptions say or you might be in trouble.
