This is a how-to enable Remote Desktop on Windows
RDP or Remote Desktop Protocol is a protocol that Microsoft developed for users to better remote control their machines. This protocol is very lightweight (bandwidth wise) because it was developed when the internet was still a child, and therefore with slow connection speeds.
So, to activate this protocol, just follow this:
Click Start, point to Control Panel, System. If you're using Windows 7, Windows Server 2008 or Vista, you should click on Remote Settings.
You should be able to find a tab named Remote. Tick the Allow Connections to this Computer. Select the users you want to give access and click ok to accept all your changes.
After that, you just have to use your Remote Desktop client to connect to your server. Login and enjoy!
