Vista - VPC 2007 SP1, Virtual Machine Additions causing problems.

I just upgraded my Virtual PC 2007 installation to VPC2007 SP1. The
installation of the new system appeared to be successful. My host is
Windows XP SP3. I then booted my guest (Vista, no service pack) and all
appeared normal. Next I installed Virtual Machine Additions in my guest
figuring that I should update the Additions along with Virtual PC (I had
the Additions from the old version of Virtual PC installed previously).

Now, alas, my guest is nearly unusable. It is extremely slow and Virtual
PC consumes 100% of one of my cores (my host is a dual core machine). It
certainly appears that Virtual Machine Additions is at fault because the
guest ran fine before I installed the new version of the Additions.

What should I be looking at the hopefully fix this problem? Uninstalling
Virtual Machine Additions doesn't seem like the right answer even if it
works.

Don't upgrade the Vista guest until it is at service pack level one. Until
you do reinstall the vmadds for VPC 2007 rtm. If you need the vmadds .iso
for VPC 2007 rtm you can download VPC 2007 from
http://www.microsoft.com/downloads/d...displaylang=en
and install in a vm. That will extract the vmadds.iso. Naturally, VPC 2007
won't run in a guest but it will install and that is the easiest way to get
the .iso.
