About application preferences

Application preferences apply to all virtual machines that you create in Microsoft Virtual PC. They are specified for the Virtual PC application rather than individual virtual machines. Application preferences determine behavior, such as sound, CPU usage, visual display, and other behavior that applies to all virtual machines in Virtual PC.

The following table provides a description of each application preference.

Select	To
Alert Behavior	Determine if alert messages will be displayed. In Virtual PC, many alert messages contain a Don't show again option. If you select this option, the alert will not display again in Virtual PC. However, if you want alerts in Virtual PC to be displayed, you can click Reset in the Alert Behavior application preference and the alerts will display.
PC Behavior	Suspend all activity in other virtual machines except the active virtual machine. This may provide better performance when running multiple virtual machines. Restart, the next time you start Virtual PC, all virtual machines that were running when you last closed Virtual PC. To do this, click Restore PCs at launch.
Full Screen Mode	Determine the behavior of the video settings on your Macintosh when running a virtual machine in full-screen mode.
Virtual Switch	Determine which Ethernet adapter to use with a virtual machine that is set to run with the Virtual Switch networking option.
Sound	Determine the behavior of system sounds on all virtual machines.
CPU Usage	Determine how to divide processing resources between Virtual PC and other applications that are running simultaneously when Virtual PC is not the active application on the Macintosh.

Toolbar	Select the items that will appear on the Virtual PC toolbar at the bottom of virtual machine window.
