Windows uses 20% of your bandwidth !

Microsoft reserve 20% of your available bandwidth for their own purposes

(suspect for updates and interrogating your machine etc..)

Windows uses 20% of your bandwidth !

Here's how to get it back:

Click Start-->Run-->type "gpedit.msc" without the "

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%.
Works on XP Pro and 2000.

Other OS not tested.

Clarification about the use of QoS in end computers that are running Windows XP
As in Windows 2000, programs can take advantage of QoS through the QoS APIs in Windows XP. One hundred percent of the network bandwidth is available to be shared by all programs unless a program specifically requests priority bandwidth. This "reserved" bandwidth is still available to other programs unless the requesting program is sending data. By default, programs can reserve up to an aggregate bandwidth of 20 percent of the underlying link speed on each interface on an end computer. If the program that reserved the bandwidth is not sending sufficient data to use it, the unused part of the reserved bandwidth is available for other data flows on the same host.

For more information about the QoS Packet Scheduler, see Windows XP Help. Additional information about Windows 2000 QoS is available in the Windows 2000 technical library.

Correction of some incorrect claims about Windows XP QoS support
There have been claims in various published technical articles and newsgroup postings that Windows XP always reserves 20 percent of the available bandwidth for QoS. These claims are incorrect. The information in the "Clarification about QoS in end computers that are Running Windows XP" section correctly describes the behavior of Windows XP systems.

Windows XP Quality of Service (QoS) enhancements and behavior
