When Windows XP is run as a guest without Integration Features, guest desktop resolution can be changed with Properties, but when Integration Features are enabled, that won't work -- the guest starts with a resolution of 896 x 600; resolution can be changed only by resizing the guest window; and when the guest is restarted any change is lost.
To start the Windows XP guest at a specific resolution (e.g., 1024 x 768) with Integration Features enabled, the settings file for the virtual machine must first be edited manually:
- Log off host and then back on to make sure virtual machines are shut down
- Click Start and enter "%localappdata%\Microsoft\Windows Virtual PC\Virtual
Machines"
(without quotes) - Locate the settings file (.vmc) with the same name as the virtual machine
(You may want to make a backup copy of this file for safety) - Right-click the settings file, choose Open with, and select Notepad
(If Notepad is not an option, use Choose default program to associate it) - Find the tag <resolution_height type="integer">
and change to the desired value (e.g., 768) - Find the tag <resolution_width type="integer">
and change to the desired value (e.g., 1024) - Close Notepad, saving the settings file
- Start the virtual machine
