How to Enable Windows 10 TCP Keepalive?

Windows 10 includes a feature called TCP keepalive that helps maintain network connections by sending periodic keepalive packets. These packets ensure that the connection remains active and prevent it from timing out due to inactivity. Enabling TCP keepalive can be useful in various scenarios, especially when dealing with applications or services that require a constant connection. In this article, we will guide you through the process of enabling TCP keepalive on your Windows 10 computer.

Step 1: Open Command Prompt

The first step is to open the Command Prompt, which is a powerful tool for executing commands and configuring various settings on your Windows computer. To open Command Prompt, follow these steps:

1. Press the Windows key on your keyboard.
2. Type "Command Prompt" in the search bar.
3. Click on the "Command Prompt" app in the search results to open it.

Step 2: Run Command as Administrator

Enabling TCP keepalive requires administrative privileges. Therefore, you need to run the command as an administrator. To do this, follow these steps:

1. Right-click on the "Command Prompt" app in the taskbar.
2. Select "Run as administrator" from the context menu.
3. If prompted, click "Yes" to allow the app to make changes to your device.

Step 3: Enable TCP Keepalive

Now that you have the Command Prompt open with administrative privileges, you can proceed to enable TCP keepalive. Enter the following command and press Enter:

This command configures the global TCP settings to enable keepalive packets. You should see a success message indicating that the command was executed successfully.

Step 4: Verify TCP Keepalive Status

To verify whether TCP keepalive is enabled on your Windows 10 computer, you can use the following command:

This command displays the current TCP settings, including the keepalive status. Look for the "Keep Alive Interval" and "Keep Alive Time" values. If they are not set to their default values (usually 7,200 seconds), it means TCP keepalive is enabled.

Step 5: Disable TCP Keepalive (Optional)

If you ever need to disable TCP keepalive, you can use the following command:

This command disables the TCP keepalive feature on your Windows 10 computer. You will receive a success message indicating that the command was executed successfully.

Conclusion

Enabling TCP keepalive on your Windows 10 computer can help maintain network connections and prevent them from timing out due to inactivity. By following the simple steps outlined in this article, you can easily enable or disable TCP keepalive as per your requirements.
