Unleash7 - Everything PC... Made Simple!

By default, Windows reserves 20% of your bandwidth for very few purposes to make some tools, like Windows Update, run a bit faster, but not by much. Here's how to set the bandwidth limit to 0%:
 *This tweak might not work depending on your network adapter

1. Click Start, Run and type gpedit.msc
2. In the Computer Configuration tab, expand Administrative Templates and then expand Network
3. Click on QoS Packet Scheduler
4. On the right side, double-click on Limit Reservable Bandwidth
5. In the windows, make sure it is Enabled and then set the Bandwith Limit to 0%

NOTE: Disabling this feature or Not Configuring it, the system will still use 20% of reservable bandwidth

Hope it helps!
