Increase Bandwidth by 20% in Windows XP

Microsoft reserves 20% of your available bandwidth for their own purposes likeWindows Updates and interrogating your PC etc. You can releas this 20% reserve bandwidh and speedup the download and upload limit. The service which is reserving the bandwidth is LimitReservableBandwidth which determines the percentage of connection bandwidth that the system can reserve. This value reserves the combined bandwidth reservation of all programs running on the system. Here are the steps to perform this taks.

1. Log in as a Administrator.

2. Click Start , select Run and type in "gpedit.msc"(without quotes)then hit OK. This opens the group policy editor.

3. Browse to Local Computer Policy --> Computer Configuration--> Administrative Templates --> Network -->QOS Packet Scheduler and then select LimitReservableBandwidth in the Right Pane.

4. Double click on Limit Reservable bandwidth.

5. It will say it is not configured, but the truth is under the 'Explain' tab i.e."By default, the Packet Scheduler limits the system to 20 percent ofthe bandwidth of a connection, but you can use this setting to override the default."

6. 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%.It works on Win 2000, XP and 2003 as well.
