The lack of a well-known, well-designed package manager for Windows has always been a problem. Too many programs, including FOSS programs, are downloaded from suspicious-looking websites with tons of ads, and every app updates itself in a different way. The crappy installation and update channels are often tightly integrated with the vendors' monetization strategies, so there's a lot of inertia.

Microsoft Store could have changed this situation, had it been better designed and better received. Unfortunately, nobody seems to use it unless they have no other choice.

WinGet looks much better, but so far it's only for developers and power users.
