installing applications by finding files on an Internet scavenger hunt, no built-in, centralized updating of applications,

Windows has the Windows store for finding and centralizing updates. Just like installing linux apps that aren't in a package manager is a scavenger hunt without centrailized updates.

I'm glad Windows store isn't popular. I'd rather not have MS in control of my apps.

having to restart your PC for your OS to update

Consumer facing distros like Ubuntu want you to reboot after OS/Window manager updates. It's simply easier and more reliable than expecting the user to know all the dependencies of their programs.

The uninstallable bloatware has become a huge hassle for me. But consumers have become used to their iPhones with the preinstalled bloatware and apple iDrive ads built into the OS constantly nagging. So of course Microsoft copied Apple.
