    I just read this, do you think its safe to do?

    Increasing Band-Width By 20%

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

    The stated path does not exist in win2k version of gpedit.msc

    Windows Xp Home does not have gpedit.msc

    The path does exist in Windows media centre and Windows XP Pro.

    You have to be even more careful when messing with GPO (group policy objects) than messing with the registry - so not for the faint of heart. It is possible to totally lock yourself out of the pc with this tool.

    You may prefer some more reliable and safer tweaks in the registry.

    Increase the DNS cache.

    In regedit

    rightclick select new>dword value
    create dword value
    cachehashtablebucketsize with a value of 1
    create dword
    cachehashtablesize value 180
    create dword
    maxchacheentrytt1limit with a value of ff00
    create dword
    maxsoacacheentrytt1limit with a value of 12d

    close regedit and restart.

    Increase the maximum transmission unit size

    In regedit


    find the key corresponding to your network adapter it will be the one with IP and DCHP listed

    create dword or modify existing
    MTU with a value 576 for dialup or 1500 for broadband.

    close regedit and restart.

    Alter the Transmission Window settings

    In regedit


    create/modify string value
    defaultrevwindow with a value of 4288

    create/modify string value
    defaultTTL with a value of 128

    close regedit and restart.

    I tried this on WinXP pro (and home, I think). It seemed to an improvement in overall internet speed.

    Most routers dont do the qos side that would be require for this non tweak to steal your bandwithd, sorry its not an effective tweak unless your router is able to do qos.
