The core browser technology is embeded in windows, even in explorer. you may find a way to uninstall IE but its core web technology cannot be removed.
explorer itself has FTP, desktop connects to the internet for live site this core web tech is what IE also uses and all windows web technology uses.
If IE can be uninstalled it meant - great they allowed the decoupling from the core web technology.
The reason why Windows is bloated - because a 1000 different people want and need 1000 different things in an OS.
Multi user, parallel IEs, multiple versions IE, embedded IE, automated apps, automated install, automated silent install on 1000 systems, automated updates included, lite version installed, virtual OS, multiple VOS etc.
People are never happy they always want something different and you cannot please all.
