Increasing Band-Width By 20%:

[vishwa2008]

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.
hope it'll help

if u think this is use full tell me i'll try posting more intresting things

Vishwa this is useful only for connections which have QoS enabled, QoS comes only as part of Ipv6, so I dont think it would affect us - atleast not until we shift to IPv6

Not True, this is a really old myth about windows.

Qos is enabled in IPv4 too.

Read this clarification from Microsoft:

Quote:As in Windows 2000, programs can take advantage of QoS through the QoS APIs in Windows XP. One hundred percent of the network bandwidth is available to be shared by all programs unless a program specifically requests priority bandwidth. This "reserved" bandwidth is still available to other programs unless the requesting program is sending data. By default, programs can reserve up to an aggregate bandwidth of 20 percent of the underlying link speed on each interface on an end computer. If the program that reserved the bandwidth is not sending sufficient data to use it, the unused part of the reserved bandwidth is available for other data flows on the same host.

thanks for the info guys

[coolpcguy]

@veagles QoS is provided by IP protocol, and supported by backbone routers, not by Operating System(Windows/mac/Linux). AFAIK IPv4 protocol doesn't support QoS.
