Microsoft reserves 20% of your available bandwidth for its own purposes (suspect for updates and interrogating your machine etc.) Here’s how to get it back:

Click Start / Run
Type: gpedit.msc
This opens the group policy editor. Then go to:
Local Computer Policy / Computer Configuration / Administrative Templates / Network / QOS Packet Scheduler / Limit Reservable Bandwidth
Double click on Limit Reservable bandwidth. It will say it is not configured, but the truth is under the ‘Explain’ tab:

“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%.

Was this not only in services pack 1 and lower?
I have had it disabled and enabled for me it didn't changed my download speed:(.

Hadn't Reppy posted something like this before? ^^ (no offense :wink:)

There's also another way of making sure the QoS doesn't reserve 20% of your bandwidth -> Link (http://www.sb-innovation.de/27021-post7.html)

@Logitech: QoS reserves that % of your bandwidth but it often doesn't use it... the speed boost may be more noticeable if you had the "QoS packet scheduler" installed (network connection properties) before.

Ok that could be the reason why It never worked for me.
Still glad that it wasn't enabled for me at default.

I personally only have the TCP/IP protocol installed in the connection's properties :tongue:

If you're part of a LAN and need to share stuff, you'll also need to have the "Microsoft network client" and "MS file & printer sharing" installed...

Well,for sure we do appreciate the help soul u got zat,but yeah Ive already posted that earlier before,anyway thanks for the effort :top:

@Logitech: I also recieved that feedback when I posted it before,so let me re-explain why you can see any difference when disabling/enabling such a service,this 20% stored inside ur cache is for error reporting/windows updater client/time & date suchronizing so those lost kbs wont make a difference for a low connection line (I mean users with strong connections can feel that difference on the spot upon disabling this service),anyway IMO its a useless service with a possibility of wasting some bandwith which can be restored back to u,so its up tya :tongue:
