Because we actually use the operating system?

Windows rots. Even a few days without a reboot and things will just stop working or be really slow. No idea why.

But if you don't clean install once every few years you'll just have a ton of shit everywhere. Programs don't clean themselves up.

Also every program has its own update mechanism. Great... now I don't just have to manage windows update, but also a few dozen other esoteric update mechanisms.

iOS and Android are self managing. Windows? Can we be for real? Why get on the internet and lie to people?
