By default, Windows XP reserves 20% of the connection bandwidth for QoS traffic? This tweak allows the setting to be altered to a different percentage of connection bandwidth? If the system uses more than a single adapter for network connections, each adapter may be set individually by navigating to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Psched\Parameters\Adapters\{Adpater-ID} rather than HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Psched
[Start] [Run] [Regedit]
Registry Key: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Psched
Modify/Create the Value Data Type(s) and Value Name(s) as detailed below?
Data Type: DWORD Value // Value Name: NonBestEffortLimit
Setting for Value Data: [Enter as a Percentage / Default Value = 20]
Exit Registry and Reboot
