In Windows 10, you can allow Remote Desktop from other systems. It will give you facility to control a target system remotely, using client machine.
When you allow your system for Remote Desktop connectivity, you actually open a port on your system which other systems in your local network can connect. If you want to secure remote connectivity, you need to enable Network Level Authentication (NLA). The benefit of this is that users need to authenticate themselves to establish remote session. In this way, your Remote Desktop connectivity will become more secure and it will prevent unauthorized users to connect your system. Microsoft also recommends you to have remote sessions only with NLA enabled.
Here are the methods you can deploy to enable NLA on your Windows system:
