Windows Live Messenger Times Out on Windows 7 Solved

So, you installed Windows 7/Windows Vista and Internet connection is working fine, and you can browse web sites normally,

But,

Windows Live Messenger/some other network or Internet activity times out!

This symptom is due to the "TCP/IP Auto-Tuning" in windows 7 and Windows Vista, which is not compatible with some network devices.

to disable TCP/IP Autotuning, open elevated command prompt, and run the below command, and then reboot your PC:

netsh int tcp set global autotuninglevel=disabled

This should disable TCP/IP Auto-Tuning and solve your problem.

Note: In case you want to undo this command for any given reason, open elevated command prompt, and run the below command, and then reboot your PC:

netsh int tcp set global autotuninglevel=normal
