Disable Vista Auto Tuning to Prevent Browser Slow-Down

June 27, 2008 by Paul Spoerry Leave a Comment

Windows Vista includes a feature, “Receive Window Auto-Tuning,” that you’ve likely never seen mentioned on your desktop, but which can cause noticeable drag and even crashing when browsing certain web sites or using some routers or other network hardware. If you’re noticing browsing glitches that only occur in Vista, the Wise Bread blog has a tip, pulled from PC Magazine’s recent issue, that explains how to turn off auto-tuning and skip the spinning blue circle of death.

To determine you current settings launch a command prompt as an Administrator (type “cmd” into the Start box, right-click on Command Prompt and select “Run as Administrator), then enter the following line:

netsh interface tcp show global

If the line Receive Window Auto-Tuning Level does not say disabled, enter this command:

netsh interface tcp set global autotuning=restricted

If that doesn’t help the simplest way to turn off auto-tuning is to enter the following line:

netsh interface tcp set global autotuning=disable

That should do it, and turning it off won’t likely have any adverse consequences. You should notice the difference in browsing speeds immediately. If you find otherwise, turn it back on with:

netsh interface tcp set global autotuning=normal
