Here’s a simple 3 minute tweak that will increase broadband speed in XP (Pro) and Windows 7 (Pro & Ultimate).

By default (even with QoS disabled) Windows reserves up to 20 percent of your connections bandwidth.

To override this reserve take the following steps.

Make sure you Log on as Administrator, not as a user with Administrator privileges.

 

Windows XP

gpedit.msc

  • Open the Run dialog box using shortcut Window + R and type gpedit.msc

 
Computer Configuration

  • Expand [ Computer Configuration ] branch

 
Group Policy

  • Expand [ Administrative Templates ] branch
  • Expand [ Network ] branch
  • Highlight [ QoS Packet Scheduler ]
  • Double-click [ Limit Reservable Bandwidth ]

 
Limit Reservable Bandwidth

  • Enabled is set by default, if [ Not Configured ] is your current setting Change to [ Enabled ]
  • Change [ Bandwidth limit % ] to 0
  • Click [ Apply ] [ OK ]

Windows 7

windows-7-gpedit.msc

  • Open the Run dialog box using shortcut Window + R and type gpedit.msc

 
Windows 7 Local Group Policy Editor

  • Expand [ Computer Configuration ] branch
  • Expand [ Administrative Templates ] branch
  • Expand [ Network ] branch
  • Highlight [ QoS Packet Scheduler ]
  • Double-click [ Limit Reservable Bandwidth ]

In Windows 7 Not Configured is the default setting.

Even though bandwidth limit (%) indicates 0, Windows reserves up to 20 % of the current bandwidth available, as seen below.

 
Windows 7 Limit Reservable Bandwidth Default

  • Change setting from [ Not Configured ] to [ Enabled ]
  • Change [ Bandwidth limit % ] to 0
  • Click [ Apply ] [ OK ]

Effect is immediate.
