Reverse-engineers defeated a Microsoft system of DRM (Digital Restrictions Management) for Windows applications.

I would cheer for them, except that even once these applications' DRM is removed, they remain proprietary software — you use them at the cost of your freedom. An unauthorized copy of a proprietary program is a rather bad thing, almost as bad as an authorized copy of the same program.

To protect your freedom, you need to refuse to run the program. And refuse to run Windows, too.

Please don't refer to unauthorized sharing as "piracy". It is propaganda for the enemy.
