WmiPrvSE.exe taking CPU 100%, Windows Update problem

Lately I have noticed that the process WmiPrvSE.exe in the task manager is consuming all my CPU cycles (about 50%, or equal to 100% on a dual core proc, every 3 seconds - see screenshot)

It's only this process, with a different PID every time, and not anything else like svchost or Dcom... I have tried many other fixes on the internet including disabling it, restarting the BITS service, and restarting computer in safe mode/messing around with Windows Update settings.

On top of that, my Windows Update will not work. I'm running Win7 64-bit Premium on an Asus laptop. When I try to use Windows Update (WU), it says 'Windows cannot currently check for updates because the service is not running' (see attached screenshot).

I can't update it whatever i do, including the things mentioned above. I've tried downloading patches from Microsoft, changing the hosts file, and doing things in safe mode and setting updates to Automatic. Also, there is weird line of text below the Automatic Update box that tells me to 'find out more about free software from (null)', which seems very suspicious to me.

I have run malware and virus and rootkit scans from AVG and malwarebytes, but nothing found. I have used process explorer to analyze but nothing is useful. I have a hijackthis log available too. I'm seriously thinking these two problems are related. Please help!


EDIT: I fixed the Windows Update problem. I read on another forum about a user who typed 'regsvr32 wuaueng.dll' into the Run box and it brought back the Windows Update service. So it worked for me too, and WU works fine now. However, the other issue is still present.

Found the problem. It was because of one service at startup:

The spmgr service, in control of the Asus PC probe and monitor app that comes with my laptop, was causing the high CPU usage from WmiPrvSE.exe. Once I disabled it at startup from msconfig, and restarted, the problem went away.

All other services had no effect.

Thanks for all your help though!
