MSFT is unlikely to do that (but they might), their idea of relevance is getting the user to rent their computer in the cloud, they're just waiting for tablets/phones to get to the point where that's ideal for them.
Windows 10 and 11 are just stopgaps until they get there.
I always felt that MSFT didn't give a moment's thought to the loss of revenue through serial key sharing, as they wanted revenue from Office, but charging for Windows by the month, or other software like Photoshop (bulk of revenue going to Adobe) spawned through an image is probably ideal for them. Why bother about the legacy billing model that probably doesn't work.
Our idea of what's relevant is not what's relevant for the shareholders.
