How to speed up your slow Internet.

Microsoft reserves 20% of your available bandwidth for their own purposes like Windows Updates and monitor your PC etc, but you can get it back

Click Start > Run and type "gpedit.msc" without quotes. This will opens the group policy editor.
Then go to : 
----> Local Computer Policy
----> Computer Configration
----> 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 i.e. "By default, the Packet Scheduler limits the system to 20% of the bandwidth of a connection, but you can use this setting to over ride the default".
So the trick is to ENABLE reserveable bandwidth, then set it to ZERO. This will allow system to reserve nothing, rather than the default 20%. It works on WINDOWS 2000 as well.
