A long-time favourite app of mine is Chrome Remote Desktop, Google have created a remote desktop app that works in your web browser on any computer, and an app for iOS and Android. This means you can control your Computer from anywhere on virtually anything provided it's powered on and you have internet access!!
I'll walk you through the process of setting up the remote access client on the computer you want to control, and then how to control it from a computer via the Google Chrome web browser and via the mobile app, also consider subscribing if you enjoyed my content.
