Windows only: If you're eager for a simple, non-browser, quick-starting app that will let you get remote desktop access to your mom's desktop, your struggling friend's laptop, or nearly any other machine, Ammyy Admin is just about perfect for your needs. The 128KB, no-install app opens and gives you a dedicated client ID number. To connect as the administrator, you simply enter the client's ID's number, choose a connection speed optimiser (if needed), and hit "Connect," while the client only has to hit "Start." Unless you use its sister private router product, Ammyy Admin will route its screen-sharing traffic over the developer's servers, so work that requires privacy shouldn't rely on Ammyy. Still, for keeping it simple with one-time connections—or even regular hook-ups, through Ammyy's Windows service option—Ammyy is worth checking out. Ammyy Admin is a free download for Windows systems only.
