Putini dintre dvs. stiu ca マイクロソフト a rezervat pentru sistemul de operare Windows XP、o banda de Internet （bandwidth) de 20%, pentru anumite servicii ale sistemului. Windows Update、 System Error Report, etc servicii gen.
Folosind o mica setare de system, in グループポリシー, putem aloca mai putina banda de Internet pentru aceste servicii.

In primul rand, trebuie sa deschidem XP グループポリシーエディター。

始める - > 走る - > gpedit.msc - > わかりました sau Enter.

In Group Policy, mergem in meniul din partea stanga la Local Computer Policy -> コンピューター構成 - > 管理テンプレート - > ネットワーク - > QOS Packet Scheduler. Selectam QOS Packet Scheduler, iar panoul din partea dreapta cautam: Limit Reservable Bandwidth。
Dublu-click pentru a deschide Limit Reservable Bandwidth, apoi bifam casuta din dreptul “有効にする“, pentru a ne permite sa setam cat la suta din banda de Internet dorim sa o rezervam serviciilor de sistem.

By default, aceasta limita este setata la 20%, dar putem aloca 0% pentru a beneficia de toata viteza de download。

Limit Reservable Bandwidth – Explain ：

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.
