Vista - tweak to disable bandwidth limit in vista

type GPEDIT.MSC in search box

then a Group Policy Object Editor will popup.

Under Local Computer Policy

click or expand Adminstrative Templates

next click or expand Network

then click on Qos Packet Scheduler (remember dont click on the expander here just click on Qos Packer Scheduler)

Now double click Limit reservable bandwidth

(You will see Not configured which is the default settings but in reality Vista has already taken 20% of your bandwidth to reserve for updates and stuff like that.)

Now click on Enabled then in the Bandwidth Limit (%) set it to 0 then click apply then reboot.
tried it and it does work. no big dramatic gain but it works

thanks
worked for me but that could just be wishful thinking

actually its in start / run / gpedit.msc / computer configuration / administrative templates / network / Qos packetts / limit reserve bandwidth. You have to make it idiot proof. good tweak though thx

Hey Hclarkjr,

Im sorry to say we already have this tutorial since last year...

QoS Bandwidth Reserve Limit

It's one of the Windows myth
This qos regards only the way of running apps, and the 20% reserved are really reserved by Windows only in case of update or some other windows aplications run automatically.
When there are no Windows apps running on your back, 100%, of course, are dedicated to your apps.
