Speed up your windows RDP

If you are on windows 7, or windows vista, and remote control a desktop, I've just found, and applied this command:

netsh interface tcp set global autotuninglevel=disabled

open cmd, and copy paste this command

I got amazing speedup on refreshing my screen, even with 2 RDP connections opened. No more pain of drawing interface.

You apply this on YOUR PC, not RDP.
