 +===== Introduction =====
 +Windows Vista throttles the network interfaces while audio is playing in order to maintain audio quality and prevent network interrupts interrupting media playback. ​ By default, this limits the network receive speed to 10% of its maximum - 100Mbps on gigabit ethernet, and 10Mbps on fast ethernet - but since Vista SP1 you can alter that percentage by changing a registry value:
 + ​HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile\NetworkThrottlingIndex
 +Change it to a value between 1 and 100 (and then reboot) to set the maximum downstream network bandwidth that can be used while playing audio. ​ Not an ideal solution, but better than having none at all...
