On Microsoft operating systems, by default, combined bandwidth reserves are active for all programs running on the system. Because of this, you find yourself having up to 20% of your "lost" internet bandwidth for each download and upload. The operating system reserves a percentage of bandwidth for network controls and management. However, you can ?recover? this reserved band by disabling it or (for those who do not want to disable it) by decreasing the percentage of band reserved for the operating system.On Windows 7 you can easily disable or change the bandwidth reserved by the operating system and to increase therefore the speed of the internet connection.
can perform this procedure only on versions of Windows 7 where you can start theLocal Group Policy Editor, i.e. the Windows 7 versions Professional, Ultimate and Enterprise, while it is not possible to do it on the Windows 7 Starter, Home Basic and Home Premium versions as the editor is not available.
The steps are:
- start theLocal Group Policy Editor writing gpedit.msc in the form Search for programs and files of the Windows start menu and clicking on the search result obtained;
- click on Computer configuration » Administrative models » Network » QoS package scheduler;
- right click on the item Limit reserved bandwidth and select Edit;
- in the window that will open click on enabled, set the value Bandwidth limit to 0 to disable the bandwidth reserved by the system (see figure below) or set it to the desired value (to leave a percentage of reserved bandwidth) and click on apply;
- restart Windows for the changes to take effect.
The method described also works on Windows XP Professional and the products of the Windows Server 2003 family.
Note: If a bandwidth limit is set in the registry for a specific network card, this setting will be ignored when configuring the network card.
