Increease your Internet tools by 20%

Microsoft reserves 20% of your available bandwidth for their own purposes
like Windows Updates and interrogating your PC etc
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.
