Startup Account problem

I don't know if this is normal, but I have one account that doesn't show up in 'user accounts' when logged in on my 'main' account... it's set to computer administrator. This is the account that is used in safe mode.

For the past couple of days, when I boot/restart windows (xp pro), it starts in this account, instead of my usual, 'main' account (also computer admin).

I've run virus scans, spybot, & mbam - they found nothing; have Avira, Comodo firewall and Spyware Guard running. This problem started about the time I downloaded these last 3 programs (while running Zone Alarm - yes, uninstalled ZA to run Comodo )...and had a power outage while the pc was on.

How can I get windows to start up with my 'main' account?

Never mind - someone suggested tweakui to set which account to boot.
