Following a hard drive crash on my old machine, I have recently purchased a
new PC which came with Windows XP Home pre-installed.

I am the only user.  I have successfully gotten rid of the "click on your
picture to log in" Welcome Screen (or whatever it's called).  Now, I have
the Windows Login dialog box that pops up at startup.

I know that this is an install-time option (to disable that box when there
is only a single user on the machine).  Is there a way to disable it so that
the startup completes without intervention *without* having to reinstall
Windows XP?

Thanks for your assistance, and please let me know if my problem description
is unclear.
