How To Increase Internet Connection Speed in Windows Xp, Windows 7

This is a nice little tweak for Windows XP, Windows 7. Microsoft Windows reserves 20% of your available bandwidth for their own purposes!!(Think they it use it for updating and interrogating your machine blah blah)
Follow the steps below in order to get it back!!
Click Start-->Run-->type gpedit.msc

This opens the group policy editor.
Then go to:Computer Configuration-->Administrative Templates-->Network-->
QOS Packet Scheduler-->Limit Reservable Bandwidth.

By default, the QOS Packet Scheduler limits the system to 20 percent of the bandwidth of a connection, but you can use this setting to override the default.
Double click on Edit Plocy Settings

A new Dialog Box appears and It will say it's not configured, So the trick is to ENABLE reservable bandwidth, and set it to ZERO (This will allow the system to reserve nothing, rather than the default 20%) See the Picture Below:

Note:100% Working and tested on windows XP, Windows 7, Windows Vista, 2000 and ME.
