{INCREASE YOUR BANDWIDTH BY 20%}

Windows uses 20% of your bandwidth! Get it back

A nice little tweak for XP. M*crosoft reserve 20% of your available
bandwidth for their own purposes (suspect for updates and interrogating
your machine etc..)

Here's how to get it back:

Click Start-->Run-->type "gpedit.msc" without the "

This opens the group policy editor. Then go to:

Local Computer Policy-->Computer Configuration-->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 :

"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%.
