Incerase Internet speed in Wndows

Microsoft reserves 20% of the available bandwidth for their own purposes like Windows Updates and interrogating your PC etc.

You can get it back:

Click Start, Run and type "gpedit.msc" without quotes. This opens the Group Policy Editor.

Go to:
-> Local Computer Policy
- Configure PC>
-> Administrative Templates

-> Network

-> Scheduler Packages QOS-> limit bandwidth use.

Double-click the bandwidth limit reserved.

I will say that has not been set, but the truth is under the tab "explains" that "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 Standard ".
So the trick is to allow the reserved bandwidth, then set it to zero. This will allow the system to reserve nothing, rather than the standard 20%. It works well on Win 200
