This is actually just about the exact opposite of proper testing and verification. The main problem is the idea of running compiled programs unmodified: programs that had an entirely different OS target when they were built. If this is what Microsoft is doing then they’ve invented an environment that could not possibly have been anticipated by those who built the original programs. Anything could happen. And worse, it’s not clear who to send the bug report to when things go wrong.
