As of late 2019, Microsoft makes a majority of their income off Office and Azure services:I read Microsoft only gets 11% of its revenue from selling the OS-and the vast majority of that comes from Dell,HP,etc.
I bet the next version will be called Microsoft Free as they are already selling stuff right from the OS (advertizing,MS Store,etc).
They may still charge a commercial license fee to Dell and the big box makers,but free for the rest of us.
Most driver updates for muggles likely comes from Windows update rather than the store. And even then, I've only seen the driver application (e.g., NVIDIA Control Panel) coming from the store.Wonder if they force people to use windows store for all driver updates.
