Welcome screen no longer displayed after last automatic Windows up

Hello,

I have winXP Pro SP3 with one single user defined, which is an administrator,

without password.

Until the last automatic windows update (on 04/08/2010) the Welcome screen

always appeared, but the logon happened automatically, as expected when one

single user is defined without a password.

Now, instead of the Welcome screen, the regular logon box appears, on a

black background, and it accepts the empty password and then, after some

time, displays the desktop.

Both using the welcome screen and Fast user switching are enabled.

I found a Microsoft hotfix http://support.microsoft.com/kb/817164/en-us

that is supposed to solve this problem, but the article also states that it

was solved in SP2.

This did never happen before,

is it possible that the automatic update caused this behavior ?

How can I revert back to the old behavior ?

Is it safe to install the above hotfix, although I am in SP3, or better

restore to the

System restore point created before the last automatic update and then

cancel further automatic updates ?

Thanks & Best Regards,
