I use Windows XP Pro.

Each time I boot, the system opens the "Log on to Windows" screen and
ask me for a password and I have to click OK to continue the boot
process.

Being the sole user of my computer, I really don't need this feature
which adds time to a boot process that is long enough in my opinion.

How can I disable this feature in order to make a clean boot each time
I turn on my computer.

Thank you
