How to add an entry to startup?

This is for WinXP and in classic Start menu
1. Right-Click on the taskbar
2. Scroll to "Properties"
3. Click the "start menu" tab
4. Click "Customize" for the classic Start menu
5. Click the "Add" button to add the program you want to appear on the Start Menu.
6. Browse for the program and click next
7. When asked which folder to place the icon in highlight the "Start Men" Folder.
8. Click Next-->Finish-->Then Apply or Ok button.

See if the program (while you have it up) has an Options tab (sometimes it may be called Program) which has a checkoff to load at startup.

If not, add its' executable to the Startup folder which you'll find at:

Documents&Settings - All Users - Start Menu - Programs
