MORE INFORMATION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may
require you to reinstall your operating system. Microsoft cannot guarantee that you can solve
problems that result from using Registry Editor incorrectly. Use Registry Editor at your own
risk.
After you upgrade your computer from Microsoft Windows 98 to Windows XP, and then you log on to the computer for the first time, Setup disables all of the program files (all .lnk and .exe files) by removing them from the Startup folder and the
Run key in the registry, except for the "known good programs", which are not removed.
The
Restore Startup Programs option is located on the
Startup tab in the System Configuration Utility.
This option is available only when one or both of the following conditions occurs:
- One or more values are identified and moved to the DisabledRunKeys registry key from the Run key (in the registry).
- One or more programs are identified and moved from the Startup folder to the two disabled Startup folders.
When this option is available, if you select it, the "Startup Programs Removed During Setup" window opens and displays a list of all of the disabled programs, which includes their return locations (when they are enabled). This option enables you to restore one or all of the files that are listed as disabled. If you enable all of the programs that are listed, the next time that you start the System Configuration Utility all of the items are transferred to the
Startup tab, and the
Restore Startup Programs option is unavailable.

The values that are removed from the
Run key are transferred to the following registry key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Setup\DisabledRunKeys
Each value that is under this key corresponds to a run item (program) that had been disabled by Setup. The format for the values is the same as the original values in the following registry key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
When you restore these values by using the
Restore Startup Programs option, they are moved from the registry value in
DisabledRunKeys back to the
Run key.
The startup programs are moved to one of the following hidden folders:
- Systemdrive\Documents and Settings\User\Start Menu\Programs\Disabled Startup
- Systemdrive\Documents and Settings\All Users\Start Menu\Programs\Disabled Startup
These folders correspond to programs that have been disabled from the "User" and "All User" Startup folders. When you restore these programs by using the
Restore Startup Programs option, they are restored to the corresponding Startup folder.
