This application is a free and open-source screen mirroring application that allows control of an Android device from a Windows, macOS, or Linux desktop computer. The software is developed by Genymobile, which also developed Genymotion, an Android emulator.
It does not require any root access, but you need to make sure you enabled adb debugging on your device and the Android device requires at least API 21 (Android 5.0).
For Windows, you can download the file right here.
Just plug the USB cable into your device and open the .exe file and you're done to use.
