Microsoft Window reserves 20% of your available bandwidth for its own purposes, i.e. Window Updates. Basically, this reduces the speed of the Internet by 20%. This is an old and popular trick on Windows XP. You can simply get that reserved 20% of bandwidth back.
If you don’t want your bandwidth to be wasted, then get it back.
Follow the below Procedure to Increase Internet Bandwidth by 20% in Windows XP:
1. Open Group Policy Editor, Click Start –> Run –> type “gpedit.msc” without the quotes.
2. In Group Policy Editor, Go to Local Computer Policy –> Computer Configuration –> Administrative Templates –> Network –> QOS Packet Scheduler.
3. Now, In Qos Packet Scheduler check On right Pane (Right Side) for “Limit Reservable bandwidth” in setting Column.
4. Double-click on Limit Reservable bandwidth. It will say it is not configured, but it’s configured to use 20% of the bandwidth. To know more about this, Go to the Explain Tab.
5. Now, Change the Default setting “Not Configured” to “Enable“.
6. Select the “Enable” Radio Button Then Set Bandwidth Limit To ZERO ( 0 %), instead of 20% and After making it as 0%, now Click on Apply to save the setting and Click on OK.
Now you have 20% More bandwidth.
