How do you change startup programs?

[viswanath]

To add/remove programs to start automatically use the "StartUp" Menu on "Start" "Programs". On XP is located on X:\Documents and Settings\XXXXX\Start\Programs. Where XXXXX is the user name or "All Users".
To check/remove programs that start automatically but are not located on the "StartUp" folder you can use the "msconfig" and select the "startup" tab and uncheck the programs that you do not want to load or the "regedit" on "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run" and delete the keys for the programs that you don't want to load.
...WARNING...be extra carefull with the "regedit" since this DB is the windows guts.
