SPEED UP YOUR INTERNET BY 20%

Speed up your internet 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 Vista & 7 as well.
