SPEED UP BANDWIDTH FOR ABOUT 20%
By Default, Windows uses 20% of your bandwidth for its own purpose such as windows updates, But here's how to get your 20% bandwidth from windows.
Instruction:
1. Click Start > Run.
2. Type "gpedit.msc" and it will open the group policy Editor.
3. Go to Local Computer Policy > Computer Configuration > Administrative Templates > Network > QOS Packet Sched. > Limit Reservable Bandwidth.
4. Double click Limit Reservable Bandwidth and you will see that it is not Configured, but you will see a note on Explain tab 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 the default."
What you need to do is:
5. ENABLE the Limit Reservable Bandwidth then set it to ZERO PERCENT (0%).
by doing this, the System will no longer limit your bandwidth to 20%.
