Welcome to Vista Forums.
Sorry, but there is no way for a desktop without a backup UPS device.
You can easily create a Power Options
shortcut and place it where you like for easy use though. For example, in Quick Launch.
Open the Control Panel (Classic View)
Right click on the Power Options
Click on Create Shortcut
This will create a Power Options shortcut on your desktop that you can move to where you like. You can also do this with any other icon in the Control Panel.
Hope this helps,
