Last months report hit the web about old games no longer working on Windows 10 because Microsoft decided to refuse to support SafeDisc and SecuROM because these rootkit-like DRM solutions would make Windows 10 less secure.
This month Microsoft has taken it a step further by rolling out a security update that removes support for the SafeDisc DRM from Windows Vista SP2, Windows 7 SP1, Windows 8, and Windows 8.1.
The KB3086255 patch turns off the service for the secdrv.sys driver to make Windows more secure because this type of DRM bypasses Windows' built-in security features and could make your system more vulnerable to malware.
Microsoft acknowledges that disabling the SafeDisc DRM driver will break support for a wide variety of old games. Details on how to temporarily (or permanently) enable SafeDisc can be found at Microsoft's website.
