Cause: This symptom is noticed when you log in for the first time after upgrading from Windows 98 or ME. Windows XP will remove all programs from the startup list, which it ‘feels’ are not compatible.
Solution: Click Start > Run, type in “msconfig” and press [Enter]. Click the Startup tab. Select the “Restore Startup Programs” option and click OK. Restart the computer. (This option won’t be available if Windows XP Setup did not disable any startup programs.)
