Vista Tweak - Cablenut Setting

Windows Vista has a self tuned RWin [Receive Window], and it works fine, Microsoft hasn't released much info about specific TCP registry keys yet, but I've been testing some of the keys from Windows XP. Turned out the DefaultSendWindow also works with Vista.

The things you need to do if you have Vista and cant reach 90% of advertised speed is


1. Make sure TCP autotuning is enabled, go to start-run paste this
netsh int tcp set global autotuninglevel=normal
and hit enter.

2. Download and install Cablenut.

3. Disable UAC, go to start-run and type msconfig, click on tools tab and scroll down to "disable UAC" click on it and then click Launch. Reboot your computer.

4. Download and unzip this upload tweak, just click on the ccs file and click save to registry in adjuster. If cablenut asks for an OS when your trying to apply the settings, use Windows 2000. Reboot your computer.

5. Test speed your speed at TestMy.Net.
