Fast up you internet connection!

I found this trick while messing up with group policy editor.

That ...Microsoft reserves 20% of your available bandwidth for their
own purposes like Windows Updates and interrogating your PC etc. same
issue is with all Microsoft OS by default.

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, and 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. How did you like it? Please comment.

Note: This trick works only for windows xp sp2 professional and
windows 2000 professional. It does not work on windows xp sp2 home
edition As there is no way to edit group policy editor.....
