A nice little tweak for XP. The software manufacturer reserve 20% of your available bandwidth for their own purposes (suspect for updates and interrogating your machine etc..)
Here's how to get it back:
Click Start-->Run-->type "gpedit.msc" without double qoutes
This opens the group policy editor. Then go to:
Local Computer Policy-->computer Configuration-->Administrative Templates-->Network-->QOS Packet Scheduler-->Limit Reservable Bandwidth
Double click on Limit Reservable bandwidth. It will say it is not configured, but the truth is under the 'Explain' tab :
"By default, the Packet Scheduler limits the system to 20 percent of the bandwidth of a connection, but you can use this setting to override the default."
So the trick is to ENABLE reservable bandwidth, then set it to ZERO. This will allow the system to reserve nothing, rather than the default 20%.

You are aware that this is somewhat a Myth. Windows doesn't actually reserve 20% of your bandwidth all the time, it priorities 20% to programs that request high priority access to your network connection. This is part of QoS.
100% of your connection is always available, however if a high priority program requests bandwidth Windows will force at least 20% for that programs use.
