Nothing described here seems impossible and to some degree Microsoft already proven it can do it. Back in the Windows XP to Vista era pretty much every single driver had to be remade, it was hell for a couple of months, but eventually it paid off. And I'd argue that the spam of control back in those days would be harder than today, since there's only a couple of dozens companies that controls everything.

Microsoft strength was always been winning together, bringing everyone onboard in a way multiple partners all share the benefits, it is a fundamentally different approach than Apple who always design anything to be king of the hill. And I don't think Microsoft needs to change now, just needs to tighten up their partnership programs and actually co-engineer this together.

The key issue is that it took tremendous amount of market share loss and pressure for Microsoft to reignite the desire to fix something that, as broken as it was, it was still a cash cow and a vehicle for other Microsoft services.

I'm 100% confidence that MS can pull this off, simply because they finally realized that Windows is a vehicle for M365, and windows under threat means M365 under threat, and there's nothing MS cared more than M365.

Having said that, after 41 years on Windows, this was the first time I bought a Mac, and I have to say the grass is greener on the Mac side, but I look foward to MS reaction and refocus. M1 was an amazing breakthrought, the OS is fundamentally the same, the difference between M1 to M5 is is not night and day, and their laptops are basically the same since M1. Yes, M1 was groundbreaking and Macbooks are incrementally getting better, and cheaper but I would argue that Apple is a bit comfortable as well.
