Which operating systems support Windows Media DRM?
The Windows Media DRM run-time client is supported on several operating systems. Depending on the operating system, either version 1 is supported or version 7 and later are supported. The difference between the two is that version 1 licenses offer more reach (for example, the Microsoft Windows 95 operating system) but fewer capabilities (for example, licensing models are more restrictive) and limited security functionalities. Version 7 and later licenses offer greater flexibility and security enhancements, but are available only to newer operating systems.Regardless of which licenses the run-time client can use, Windows Media Rights Manager 10.1 can issue licenses in all of these formats (version 1, version 7.x, version 9, and version 10.x) to all run-time clients on these operating systems.
