Many people know that Windows has one or more startup groups were they can place programs to run automatically when the computer is turned on. With Windows NT there is a startup group for each user as well as a general startup group or all users. These groups or folders can be examined with Windows Explorer. Less obvious is the fact that there are also registry settings that affect which programs start up automatically. This is in addition to the startup groups.
Many installation programs place entries here without even telling the computer user.
It then provides a listing of programs which will start whenever you boot up. See you there. Look for the current month.
