I have an application that needs to run continuously on my Windows XP Pro system. I can place it in my Startup folder and it will start when I reboot the machine. My problem is that during a power fail, when the machine automatically reboots, it stops at the login screen. This machine is very secure. It sits in my office, and no one can touch it but me. Basically I want to reboot without having to login in any manual fashion. Even if I remove my password, I still have to click me user icon to login. I want the computer to reboot and login absolutely unattended. I used to be able to do this with Windows 98. Thanks in advance! Mark
