This problem can occur after you perform any of the following actions on a computer that has Windows XP preinstalled by a computer manufacturer (also known as an Original Equipment Manufacturer, or OEM):

This is also known as performing an in-place upgrade or an in-place installation.
- You repair Windows XP by starting your computer fromthe Windows XP CD-ROM, pressing ENTER to set up Windows XP, and then pressing R to repair the selected installation.
- You upgrade the Windows XP Home Edition installation that was preinstalled by your computer manufacturer to the retail version of Windows XP Professional.
This behavior can occur if the Undo_guimode.txt file is present in the Windows\System32 folder on your hard disk when you perform any of the actions that are listed in the "Symptoms" section on a computer with Windows XP preinstalled by a computer manufacturer.
