Even their own users reject change. Ask Windows 10 & 11 users what they think of the windows store. Sure its a poor excuse of a package manager, but they unironically prefer to just download exes off websites it is not fuckin normal lol

Don't get me wrong, certain apps and games I've gotten off that store when I still used Shitblows weren't totally terrible.
Really, the only reason it exists on desktop was in hopes that UWP's (doubt they're even called that anymore) would cross over between Xbox and Windows platforms.
As we've seen, that didn't pan out.
Only good application of UWP I ever experienced was installing retroarch on an Xbox in dev mode 😈
