Same message here. Bought a Medion Akoya less then a week ago with Vista Home
Premium preinstalled. Yesterday Vista simply froze less than a minute after
logging in. No CTRL-ALT-DEL worked, couldn't shutdown, programs would not
close. All I got was a repeated black screen with the message "Logon Process
has failed to create the security options dialog.". I have been running XP on
another machine for years and I get the impression that Vista is just another
step away from the originally stable NT. Couldn't find any useful information
in a google search or Microsoft.
I ran CHKDSK which did not find any errors. Ran a virus scan with no results.
I could remove 2 programs that I had installed but it did not make a
difference, Vista keeps freezing after 1-2 minutes.
