I have a notebook Core 2 Duo 2.2 and 4 Gb of ram with Vista Enterprise x64
SP1 running on top of it.

When I install the Virtual PC 2007, one of the cores shoot's to 50%, even
without taking the Virtual PC to work!

I jut finish the installation and the cpu is immediately rises to 25%(50%
for the core).
I uninstall and the CPU drops to 2%

I thought that SP1 would solve the problem, but....

Anyone as a sugestion?

Which process is causing this?

The process is the System... One or two
threads(ntoskrnl.exe!KeReadStateQueue), I don't remember, do all the work.

I am having a similar problem. My installation isn't finishing, and the
system.exe process is chewing 50% of the cpu-recources.

PS: I'm running Vista Business SP1, on a DELL Precision M4300.

Processor: T8300
RAM: 4gb
HDD: 64GB SSD

I am experiencing a similar problem. After installing VPC 2007, my cpu usage for the System process averages about 10% (without a virtual machine running). I have tracked this to the "Virtual Machine Network Services" service on the network card. If I disable this network service or uninstall VPC 2007, the System process returns to < 1% cpu. I have tried many Broadcom drivers, but none of them have resolved the issue. I also verified that this network service is enabled on my wireless card. The wireless card does not cause a problem, so I am assuming that this is a Broadcom Network driver issue. I have also reloaded the OS...still not resolved.

Any help would be appreciated.

Thanks,
