Just found this post on a newsgroup… i feel his pain.

I'm a network admin for a poor underfunded school. The children would love to use their computers oh yes, but SOME $#@^#@^#@&#@%$$#@ @#%!@^$#@^!#@^#@^$#@^$@$#^ VISTA $#@^$@^@ and some $#@^@##^@$#$#@$#@^$#@ HP BRILLIANT MINDS GOT TOGETHER.
The merging of the HP 6515b and Vista is the most horrific combination ever conceived. I should slay these computers on a sacred altar while covering myself in Holy Water. THIS MODLE SHOULD BE NAMED THE "666." WHAT A PILE.
Ok- now that my blood pressure is returning to normal let's get to my problem.
I too cannot log in on any account unless I go into safe mode. Then I decide to disable the credentials manager - > specifically the fingerprint reader as 23587250723032 kids have used the thing and the HP engineer probably didn't expect that to happen when he programmed that "feature" into this fetid product.
Anyway - I'd love to disable it all, but it keeps giving me errors that "The Security Manager doesn't want to do that right now" or "Can't be contacted." GET THE ****ING THING OUT OF BED GOD DAMMIT IM THE GOD DAMN ****ING ADMIN AND I CANT EVEN LOG IN MY OWN ****ING COMPUTER YOU PIECE OF ****. **** YOU HP AND **** YOUR MOTHER BILL GATES. WE WERE BETTER OFF WITH XP BUT NOW WE CANT EVEN BUY IT BECAUSE YOU IDIOTS WANT TO FORCE US WITH THIS ****.
**** **** **** **** **** IM GOIN TO GO PISS ON THIS COMPUTER
/SLAM.
PS: **** YOU
