Increasing Band-Width By 20% for batter Net Speed

Microsoft reserves 20% of your available bandwidth for Windows Updates and interrogating your PC etc

To get it back:
cl!ck 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 cl!ck 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.
