Save internet bandwidth
Secure your bandwidth of internet
Microsoft reserves 20% of your available bandwidth for their own purposes like Windows Updates and interrogating your PC.
You can get it back:Click Start then Run and type "gpedit.msc" without quotes.This opens the group policy editor. Then go to:
Local Computer Policy
then Computer Configuration
then Administrative Templates then Network then QOS Packet Scheduler and then to 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 percent of the bandwidth of a connection, but you can use this setting to override the default."
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 as well.
In the registry editor (Start > Run > regedit.exe), navigate to HKEY_LOCAL_MACHINE\System\
CurrentControlSet\Services\Class\NetTrans. In the NetTrans folder you should find another
folder named "000x" in which x represents a fourth digit. Right-click on the "000x" folder
and select New and StringValue. Rename the item that appears in the panel on the right
side to MaxMTU, then double-click it to bring up the Edit String box and give it a velue
of 1002.
