Windows auto tuning level issue

Question

Where is the group policy for the TCP Global Parameters auto-tuning level? . It gives the message "The above autotuninglevel setting is the result of Group Policy overriding any local configuration" but it does not tell you where it is in the group policy.

***moved from Windows / Windows 11 / Settings***

Hello,

Thank you for posting in the Microsoft Community Forums.

The TCP Auto-Tuning level setting in Windows can indeed be influenced by Group Policy. Here are some steps you can take to find and potentially modify this setting:

1. Group Policy Editor:
   • Open the Group Policy Editor by typing gpedit.msc in the Run dialog box (Win + R).
   • Navigate to the following path: Computer Configuration > Administrative Templates > Network > QoS Packet Scheduler.
   • Look for any settings that might be related to network performance or TCP settings. Although the exact policy name might vary, it is generally under network-related settings.
2. Registry Editor:
   • If you cannot find the setting in Group Policy, you can check the registry to see if there are any related policies set.
   • Open the Registry Editor by typing regedit in the Run dialog box (Win + R).
   • Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\QoS

I hope the information above is helpful.

Best regards
