Up to middle 2000s, softwares were required to be installed either via downloading an EXE or CDROM.

Nowadays everything is cloude based including e-mails, you have zero reasons to use Windows as an end user.

Adobe is RIP and the alternative supports Linux, gaming is no longer excuse and in fact, games anti-cheat require kernel level access on Windows, that will never happen on Linux.

Companies still use Windows because they can track everything, Microsoft Teams is more than just a chat, it tracks your status, keyboard usage, interaction with teams, camera on/off during meeting, mic, etc.

Companies can build a whole profile from your Teams data.

Also, forcing engineers to use Windows to manage Linux servers has to be the most nonsense thing ever.

Make that makes sense.
