My laptop's, with Vista 64-bit business, CPU is running high constant. And when I analyzed this with ProcessExplorer I see that its the SvcHost (DComLaunch which I believe trigged by WmiPrvSE.exe) the the process thats running high. About 30-50% CPU.

I've read other forums about other ppl with same problems but non of their solutions helps. Their problems has been:
Some HP driver for printer (dont own anything related to HP)
Sound enhancement (have disable the sound enhancements)
Realtek Audio (have updated the drivers)

The threads i get for SvcHost (DComLaunch) from ProcessExplorer (PE) are:
ntoskrnl.exe!KiSwapContext+0x7f
...
RPCRT4.dll!COMMON_ProcessCalls+0x80
...

I have tried to turn off every services (non-microsoft) and every autostart programs. (I've also have debug-files WmiPrvSE.pdb and no idea what i can do with it)

When I close the application I get an error message saying the DComLaunch has stopped working and windows has to reboot (something like that)

And when i run it in safemode the error is still there only taking 15-25% CPU...
One other thing i realized that the two services that are grouped to DcomLaunch: Plug and Play and DcomLaunch.

Would appreciate some help since this is driving me crazy...

For me it was Waypoint Maploader delivered with my SonyEricsson Xperia X1 that caused this.
It did not help to uninstall Maploader, i had to do a rollback.

Just run "C:\Windows\System32\rstrui.exe"

I think it is bad that Sony Eriksson supply a software with the phone that makes your computer unusable.

Hi,
I have the same problem with cpu usage due to this wayfinder on xperia1.
I just wanted to know is there any other way of getting off this high cpu usage except windows reinstalling or rollback (i can't rollback so long, so it's not working for me anymore)?
Any ideas?
Thanx for advance!

Sorry but I have not find any other solution than rollback.

Hi
Just to let you know I also had this problem and after seeing your post, removed the Wayfinder application, but that had no effect. In the end I rolled back changes to before the Wayfinder was installed and this seems to have sorted the problem. The Xperia is a fantastic piece of kit, shame the software screws up the PC.

Has anyone tried the wmidiagnose tool?

WMI Diagnosis Utility
