The best way to make the final move and be happy in the end is a slow one, IMO.
- While still on windows, try to find alternatives to programs you use that are also available on linux and use them. Things like LibreOffice, Gimp or VLC player. You'll get to know something after you switch.
- Dual boot for a while. Try Linux as a daily driver and if something doesn't work, you still have windows to go back to.
- It's quite probable that after some time you'll realize that you haven't booted windows in quite some time and decide to repurpose the drive space for something more useful.
- Keep using Linux and get angry whenever you'll have to deal with winshit.
