There are many many outdated patterns how to do things in Windows that are cemented in public knowledge. Running random executable installers from the web giving them superuser permissions is I thing the most popular one.
How to share all user settings between system installations? How to change the logo in the desktop bar? How to add a directory to an applications bar? How to change system build-in keyboard shortcut? How to reinstall just the system keeping the programs? How to make a file run on a shortcut? Those are things I use daily, that are impossible or need some hacky programs to work on anything other than Linux, I would die if I had to switch back now.
