100% CPU Utilization with Server 2008

The other day I grabbed the latest RTM of Windows Server 2008 to try out in Virtual PC The installation process went smoothly and without incident, but once I got logged into the machine the processor of my host OS was spiking at 100% any time I would click anything in the 2008 VM. I figured installing the VM additions would resolve this, but no luck. I double-checked my power settings on the host OS and everything looked in order so I was stumped.
So when I finally fired up task manager in the 2008 machine I found the culprit: TrustedInstaller.exe was consuming 80-90% of the guest OS CPU. After some investigating, apparently this process manages software updates within Vista/Server 2008 platforms. Since I’m only planning on running this as a test OS I just went ahead an killed the process. I don’t need no stinking updates! We’ll see if this adversely affects anything else, but at least I can now run the VM at a reasonable speed.

Hi there. My name is Tom Pacyk and this is my small home on the web. I love the intersection of design, technology, and communication, which is a combination that led me to a career in sales and marketing roles at places like Zoom and ServiceNow. They're a bit old now, but I also had the opportunity to publish a couple of books along the way.

Portland, Oregon is home for me, my wife Beth, and our three kids, but I'm actually a Midwestern transplant—I grew up in the Chicago suburbs and went to school at Purdue and Illinois. When I find some free time I'm probably going to concerts, rooting for the Portland Timbers, or working on my Sunshine Burn Photography project.
