This post provide further information about How to restore the disabled startup programs after an upgrade from Windows 98 or Windows Millennium Edition to Windows XP. After you upgrade your computer from Microsoft Windows 98 or Microsoft Windows Millennium to Windows XP, the programs that previously loaded during the startup process may not be listed in the notification area (the system tray), and they no longer start automatically when you start your computer.
This behavior can occur if Windows XP removes all of the program files (all of the .lnk and .exe files) from the Startup menu and the Run key in the registry, except for the "known good programs," which are not removed. You can observe this behavior after Setup is complete and you have logged on to your computer for the first time. The files and values are moved to a hidden folder and registry key. Then, the Microsoft System Configuration Utility (Msconfig.exe) is populated with the Startup tab information.
To Fix windows Operating System issue, reinstall the values to the registry and the programs from the Startup folders:
1. Click Start, click Run, type msconfig, and then click OK.
2. Click the Startup tab.
3. Click the Restore Startup Programs option.
4. Select the programs that you want to restore, and then click OK.
5. Restart the computer.
NOTE: This option is not available if Windows XP Setup did not disable any programs from loading during the startup process.
