Being the tech-guy many times we need to help friends getting things fixed up on their computers and remote desktop sharing comes handy,
Mikogo is a free and easy to use browser based remote computer screen sharing and remote control utility for windows, unlike many other similar solutions you don't need to mess with firewall, port or IP settings to get this to work.

Mikogo Features:

• Easy browser based Screen Sharing.
• Remote Control
• Pause & Resume Transmission
• Application Selection
• File Transfer

Using the utility is pretty straight forward simply download the software, register for a free account and log-in to use, the most amazing thing is if you only need to share or broadcast your screen the other side only needs to download and execute a single no-install executable.
