Of course not. Device gaurd is the latest generation of Microsoft malware, designed to prevent users from having an actual choice as to which programs they will use to accomplish a certain task. Microsoft has been planning this “trusted computing” aka “Palladium” nonsense for years, and has no intention of letting users continue to use the those handy freeware programs they know and love. This way, developers of non-free bloated commercial crapware don’t have to actually compete. Instead, they can just tell other (presumably more talented) developers to shove it.
In other words, it’s a new universal form of DRM. By “universal”, I mean that this DRM effects every program on your system, not just the ones made by commercial devs who don’t care about the users’ freedom.
Don’t beleive me? Richard Stallman, found of The Free Software Foundation posted his reaction to TR years ago. Everyone should read it.
