Windows Virtual PC is slow!

I am extremely annoyed with Windows Virtual PC.

It is markedly slower than Virtual PC 2007. And startup times are six to ten times worse.  Same host, same VHD.  Painfully slow.

I have witnessed this on three different host machines.  I’ve seen other complaints of this online, but all of the suggestions of help completely miss the point.

There are some threads that suggest that it is caused by aggressive CPU throttling.  In a comment on a post, Virtual PC guy suggested that installing SETI@Home might solve the problem.  Seriously?

Virtual PC 2007 didn’t suffer from this problem, so I’m not going to bother with that.  It would be great if I could find confirmation that either:

  • Microsoft decided that Windows Virtual PC needn’t support laptops.
  • There is a new bug or major flaw in Windows Virtual PC that is going to be fixed.

I have rolled back to Virtual PC 2007.  I shouldn’t really care, except that I prefer the integration in Windows Virtual PC.  I suppose I should move onto VMWare, but I really don’t want to hassle with this anymore.  It works well enough for now.

Microsoft, are you acknowledging the problem?  Perhaps you can blame it on the laptop vendors, but the customer experience is just terrible.

BTW: I recorded a video of starting a Windows 7 guest using Windows Virtual PC, but a 3 minute video of a crawling progress bar seemed intolerable.
