Did you know that Windows XP reserves 20% of your bandwidth by default for other applications, meaning that you will not be able to access your browser at maximum speed, because of some other application? It sucks, right? Well now you can change it. As usual, not by any 3rd party application, but by some clever tweaking. Lets edit group policies!
1] Hit WinKey+R to open the Run… dialog box.
2] Type gpedit.msc in the Run… dialog box and hit Enter or click OK. The Group Policy window opens up.
3] Navigate to Local Computer Policy/Computer Configuration/Administrative Templates…
…QoS Packet Scheduler.
4] Now, in the right pane, double-click on Limit reservable bandwidth.
This window should open. This is how it looks like, originally.
6] Click the Enabled radio button. You will see 20% entered in the Bandwidth limit (%) text box. Type 0 instead. Zero. Not O. It should now look like this.
7] Click OK and close all the other windows. Restart Windows. You will surely notice a change in the speed.
It worked for me. Comment if it worked, or didn’t!
