How to: Install NoMachine for Windows

NoMachine is a remote desktop application. Based on the NX protocol, it allows you to connect to multiple machines remotely and control them as if you’re in front of them. Here’s how you can get started by installing Nomachine on a Windows machine.

Why NoMachine over RDP?

NoMachine has some advantages over traditional remote desktop protocol on Windows. Because it uses the NX protocol, performance is unmatched and smooth over a stable connection. It also offers better compression which makes it more efficient. Security is also another benefit with default encryption using the AES-128-GCM with support up to AES-256-GCM cipher. This makes remote sessions and user input very secure.

You can also find support for NoMachine over various platforms such as Linux, iOS, Android, Mac, and even on Raspberry Pi/ARM architecture.
