A while ago I posted about issues that people have been seeing with Virtual PC and some of the advanced power management features on today’s laptops. One solution that has been mentioned to me a number of times – but which I have never had the chance to investigate is SpeedSwitchXP. This is a neat little tool that allows you to change some of the Windows power management options that are not usually exposed under Windows.
On most systems – setting this tool to best performance will help Virtual PC immensely, with a relatively minor hit to the power consumption of the computer.
So if you are running Virtual PC on a laptop and seeing problems with slow performance, erratic performance or repeated keys inside the virtual machine – you may want to try running this tool on your host operating system.
