NOTE: The information in this article applies only to computers with Windows XP preinstalled by a computer manufacturer.
You may lose data that is stored in the All Users folder and you may lose default program templates and settings that are stored in the Default User folder after you reinstall, repair, or upgrade Windows XP. Also, Start menu shortcuts, items in the Startup group, and documents, pictures, or music files that are stored in the Shared Documents folder may be missing.
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 behavior can occur if the Undo_guimode.txt file is present in the Windows\System32 folder on the hard disk on a computer with Windows XP preinstalled by a computer manufacturer when you perform any of the actions that are listed in the "Symptoms" section of this article. The Undo_guimode.txt file is created by the wizard that runs when you first start a computer that has Windows XP preinstalled by a computer manufacturer.
Note The Undo_guimode.txt file is created by OEM Out-of-Box Experience (OOBE) when it should not be. This file should be used only by GUI-mode Setup when Setup restarts. After OOBE creates this file, when Setup performs the upgrade, it sees this file and thinks that it is restarting Setup and deletes the profiles that are listed earlier in this article.

Date Time Version Size File name ----------------------------------------------------- 08-11-2001 09:12 5.1.2600.19 927,232 Syssetup.dll
For this hotfix to work correctly in an OEM Preinstallation environment, you must slipstream the hotfix into the installation source directory (i386) before you install the operating system. If you do not do this, the original version of the Syssetup.dll file creates the \Windows\System32\Undo_GUImode.txt file, and you experience the symptoms that are described at the beginning of this article.
To slipstream the hotfix into the installation source directory, use the following steps:
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Windows XP Service Pack 1.
