Recover your bandwidth from Windows XP

A handy tutorial from the Google Community:

Windows XP uses 20 percent of your bandwidth for its own purpose (searching for updates and interrogating your machine, etc).

Here’s how to get it back:

Click Start–> Run–> type “gpedit.msc” without the quotation marks.

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 percent.

This works on XP Pro and 2000.

    Wow, clearly you have absolutely no idea what QoS is and how XP uses it.
