>I'm worried they're going to let the OS stagnate.

An OS should be stagnant. Its job is to get out of the way as soon as possible, not to constantly wow its users with cool stuff. Any user-facing change will break existing workflows and force people to learn new habits.

Change is bad. That goes for every piece of software, from OSes to web browsers to libraries. Stagnation should be your goal.

Microsoft can't do things properly. Without constant pointless novelty they couldn't convince people to buy a new version every few years. That business model has made them a lot of money, but making money and making good software are nearly orthogonal goals.

EDIT: Maybe I've misunderstood you. It sounds like you're talking about bugfixes, which certainly something Microsoft should work on.
