Debloating Nox

Nox, despite being the most feature-filled Android emulator, has a lot of negativity surrounding it due to their antics when it comes to making income off of their program. It is known for running repeated advertisments in the background, calling home and passing along system information (outside of your Android instance) as well as a vast amount of potentially sensitive data in an encrypted payload back to their multitude of servers. With the following preventitive measures, we can stop a majority of this happening as well as greatly improve the overall performance.

1. Download and Install a fresh copy of Nox. The latest version is fine (for now). If you already have it installed, that is fine too. No need to reinstall.

2. Enable Root Mode on Nox by clicking the gear icon and then checking the Root Startup box.

3. Install a new Launcher from the Play Store. ANYTHING but Nox's default. I suggest [Nova Launcher](https://play.google.com/s
