You might experience very slow internet speed at the time of peak hours and in slow internet connections. There is a method of changing system default to improve internet speed. This is achieved by changing the reserved bandwidth for the computer. Microsoft reserves 20% of the computer's available bandwidth for their own purposes like windows updates and interrogating your PC etc. You can get that bandwidth back by adjusting the settings in your PC.
Click Start then Run and type "gpedit.msc" without quotes. This opens the group policy editor.
Then go to > Local Computer Policy > Computer Configuration > Administrative Templates > Network > QOS Packet Scheduler > Limit Reservable Bandwidth.
Double click on the Limit reservable bandwidth. At the "Setting" tab limit reservable bandwidth by default shows that it is not configured. In the "Explain" tab it gives the explanation about it:
Limit Reservable bandwidth explanation:
Determines the percentage of connection bandwidth that the system can reserve. This value limits the combined bandwidth reservations of all programs running on the system. 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. If you enable this setting, you can use the "Bandwidth limit" box to adjust the amount of bandwidth the system can reserve. If you disable this setting or do not configure it, the system uses the default value of 20 percent of the connection.
By default, the Packet Scheduler limits the system to 20% of the bandwidth of a connection, but you can use this setting to override the default. You can enable reservable bandwitdh and set it to 0. This will allow the system to reserve nothing, rather than the default 20% and now 100% of the bandwidth is available for your use, making the internet more speedier.
