As others have said, essentially by being the single os for a multibillion dollar pc industry for decades. I forget exactly when the hibernate api came online... 90's?... and Microsoft has a porting layer test suite as a manufacturer that you have to pass to get that little windows stamp. All done by paid professionals and spread over the cost of the large number of pcs sold. The hal (hardware abstraction layer) is always a hard problem that takes years to get right. Write the code, write the tests, fix insane little bugs, get market momentum. Once it is solved it kinda runs itself and is a massive moat. (Apple tried this... 95? StarTrek project, os 8?) This collection of issues is why i run windows as a host os and above that run wsl (far better than mac's weird port of bsd + homebrew), local vms, and cloud servers. Unless you want to talk about the difficulty that is high dpi monitors? That has taken 5 years for 'the windows community' to shake out and i don't think linux ever will. Windows is the best solution right now for this very important problem, unless you like fuzzy text fonts. I am not a windows fanboi. Far from it. I have all the ecosystems in my house, and have professionally gone back and forth as the winds have shifted. It is amazing to me that windows has come back, credit vmware, docker, wsl, and microsoft's new openness to being a sensible first stop for developers.
