I use a handful of Windows machines regularly and don't experience most of these problems.

Your disk space issue may be related to automated backups, system restore service, and LAN caching of Windows updates. You can disable these. Disk cleanup wizard can help here too.

Edge hijack has never happened to me, although a handful of links inside windows apps/services/docs do force edge to launch (which itself causes a confirmation to make it default, which I decline)

Windows is famous for backward compatibility, especially compared to Linux or MacOS, so I'm not sure what issues you're running into there. There are some strange system dependencies that I've seen cause issues; cortana search powering the start menu search feature and disabling the swap file causing numerous invisible failures come to mind.

Faulting anti-malware is frustrating because on windows you basically have to run it, and the default one is pretty okay. Most commercial options like symantec, norton, mcafee, etc are absolutely terrible.
