How to Change the Limit Reservable Bandwidth
If your productivity is dependent on high-performance network communications, then turning off or limiting reservable bandwidth may make sense. According to this Windows tweaking myth that just won’t go away, you should change one of these settings to increase the amount of bandwidth available to your applications. Before Windows 10, users were only allowed to set a bandwidth limit for third-party applications and programs.
If a high-priority task does need bandwidth, it's in your best interest to allow those tasks to use the bandwidth and ensure your computer's security and overall health. Click the Enabled button and change the default value of 80 to a smaller percentage or to zero if you prefer to turn it off. Note, clicking the Disabled button just changes it back to the default, so that will not work. Click Apply then OK to complete the process and then exit the editor.
You can also change the bandwidth limit by editing the “Limit reservable bandwidth” entry via the Local Group Policy Editor. Most Internet Service Provides apply data caps on their Network to counteract excessive use. If your usage crosses that limit, you might have to pay extra, or your service provider may reduce your internet speed. You can limit bandwidth usage for applications, Windows updates, and other activities in Windows.
If no applications are using that 20% reserved bandwidth, Windows by default makes it available for other applications. So, at any one time, your PC is always using 100% of the available internet bandwidth. Select the bandwidth limit for uploading updates to other PCs by allowing a certain percentage of your total bandwidth. If you’re using a Wi-Fi network, you can use the router to change or set the bandwidth limit.

By default, QoS reserves 20% of the total bandwidth for high-priority tasks, while the other 80% is always available. I'm not sure if it works the same in Vista, but the XP, open the registry editor, and browse to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Psched. Create a DWORD value called NonBestEffortLimit and give it a percentage value, in your case, zero. Or, for definite 'vista safe' instructions, this may help. This won't magically speed up your internet by 20% though if that's what you're hoping for. It's only used if applications specifically ask for it, otherwise 100% of your bandwidth is available.
If you have a different reason to change the reserved bandwidth, and you know what you're doing, feel free to use one of the methods discussed above. If you want to control the bandwidth for all high-priority actions, use either the Local Group Policy Editor or the Registry Editor.

Windows will still use just as much bandwidth for updates as it otherwise would, but those updates might now slow down your higher-priority network traffic.
Usually when the network adapter makes the changes in the registry this particular setting is ignored and the default limit of bandwidth reserved is in 20 percent itself. So when the network adapter configuration is done automatically it is necessary that we should go for the manual changes in the limiting of the system reserved bandwidth. This helps in making use of our network bandwidth to greater extent. Windows uses a Quality of Service Packet Scheduler to regulate the network's bandwidth. It reserves bandwidth for high-priority tasks such as Windows Update over other tasks that compete for internet bandwidth, like streaming a movie.
