Switching from Mac to Windows:
This year I finally made the inevitable step of adding a Windows based PC to my toolbox. In this Google sheet I keep notes of useful software that I installed. 

Other valuable tools I use every day:
Notion is the free, flexible, and visual way to organize anything with anyone. Can easily be converted into your own custom system.
Evernote: Remember Everything. Modern life can be complicated. Simplify it with Evernote, the app to manage it all.
Dropbox: Get to all your files from anywhere, on any device, and share them with anyone.
Slack: a messaging app for teams.
