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.

.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

HKLM/system/currentcontrolset/services/dnscache/parameters
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

HKLM/system/currentcontrolset/services/tcpip/parameters/interfaces

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

HKLM/localmachine/currentcontrolset/services/Vxd/mstcp

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.
