SYMPTOMS
When you start a Microsoft Windows XP-based or Microsoft Windows 2000-based guest PC, you may receive the following Stop error message:

0x00000079 (0x00000004, 0x0000AC31, 0x00000000, 0x00000000)



CAUSE
This issue may occur if you complete the following tasks in this order:
 * 1) You install Windows XP or Windows 2000 on a guest PC where Advanced Configuration Power Interface (ACPI) is enabled.
 * 2) You start the operating system on a guest PC where ACPI is disabled.



RESOLUTION
To resolve this issue, manually enable ACPI in the BIOS of the guest PC. If you do not want to use ACPI power management features with your Windows XP-based or Windows 2000-based guest PC, disable ACPI in the BIOS of the guest PC (if ACPI is enabled) and then run Windows Setup to install Windows XP or Windows 2000 (as appropriate) on the guest PC.

Note By default, when you create a new guest PC in Virtual PC, ACPI is not enabled in the BIOS. You must manually enable ACPI in the BIOS if you want to use ACPI power management features.



MORE INFORMATION
The symptoms that are described in the &quot;Symptoms&quot; section of this article may occur if you install either Windows XP or Windows 2000 to a guest PC where ACPI is enabled and then start the operating system on the same guest PC or on a different guest PC where ACPI is disabled.

You do not experience the symptoms that are described in the &quot;Symptoms&quot; section of this article if you install either Windows XP or Windows 2000 to a guest PC where ACPI is disabled and then start the operating system on the same guest PC or on a different guest PC where ACPI is enabled. In this situation, the operating system starts as expected; however, ACPI power management features are not available for use with the operating system.
