netstat no TCP ports

Hi

I have noticed on my PC, netstat does not display TCP ports, only UDP ports are shown. I have searched online for this issue but couldn't find anything useful, any help or hint is much appreciated. I'm running win7 x64 ultimate

Thanks

What happens if you specify tcp as the protocol? (netstat -p tcp)

no tcp ports as well

C:\Users\nart>netstat -p tcp

I have tried virus scan with two different antivirus, malware scan as well, reported nothing.

Can this be caused by some driver ?

the following output is when booting to safe mode + networking

C:\Users\nart>netstat -na
