However we may do some tweak to optimize available bandwidth. So, here is way: 1) start -->> run -->> type gpedit.msc -->> Ok 2)Group policy page will open. 3) Now Navigate to here: Local Computer Policy -->> Computer Configuration -->> Administrative Templates -->> Network -->> QOS Packet Scheduler 4) From right pane double click on Limit Reservable Bandwidth -->> its properties page will open -->> under setting tab 5) By default , it is set to not configured, but it is using 20% of available bandwidth. Even if it set to disable, 20% of bandwidth is reserved of its own use. So, what we need to do is, make it Enable and set the bandwidth limit to 5 %, you can even set to zero %. But I will suggest you to make it atleast 5%. Actually Our windows by default keep 20% of your available bandwidth for their own purposes like Windows Updates and interrogating our PC and other works. You can reduce the limit and hence can increase boost internet speed
