It happens many time that you wish that you may have a fast internet speed Or You may want to increase your internet speed.
So let me tell you a secrete about windows, and it is that windows reserve 20% of your bandwidth for it own use (Totally bullshit).So you can increase your internet speed by taking that bandwidth from windows and use it for your surfing/downloading.
So here we go:-
Type gpedit.msc in your run command.
It will open your Group Policy Dialog Box.In that navigate to Computer Configuration => Administrative Templates =>Network => QoS Packet Scheduler.
Now double click on Limit Reservable Bandwidth and check ENABLE and then you will see a box below and notice the value in that,It will be 20% just change it to 0 (Zero).
And now just restart you machine and you will sure notice some change in your Internet speed.
