Windows Vista prevents administrative programs that need your permission to start from running automatically when you log in if they are being started from the normal "run" registry keys or startup folders.

However, you can allow an administrative program to start when you log in by creating a scheduled task.

Startup Program Unblocker

I have created a program that automates this process for you. You can download it here:

(Thanks to Microsoft MVP Laurent Gébeau of toutwindows.com for translating this program into French)

How to do it manually

Note: This only works if you are an administrator. You cannot cause an administrative program to automatically start on a standard user's desktop.

11) Click OK
