And even with app stores neither Windows nor macOS come close to the seamless experience of updating all software from a single place.
Apple had, for some time, OS updates in the App Store, but not anymore. The software update in the preferences app is a step backward in that sense - why have two ways of doing everything?
And Windows is even worse. I have at least 6 apps I need to open if I want the Windows machine to update everything.
Sadly, my evil cousin upgraded her PC with Windows and I no longer know when she needs to update or clean up the disk.
