I contacted OmniPass and you do not have to uninstall the OmniPass Software.
I
downloaded this file,
www.softexinc.com/download/UninstMSPwdProv.exe - ran
it
re-booted and I only had the 2 ADMIN Accounts I wanted. this seems to be a
problem with OmniPass Version 5.00.18 and Vista update, It has been
addressed
and fixed in Version 5.00.75 which will fix the issue. If you don't the next
time you do a Windows Update with Vista you may get the same doubled user
accounts again.

You can download the fix from the above link and double click the downloaded
file to run the file.
You also need to contact OmniPass support or your PC maker to inquire about
getting the latest version of the OmniPass software.
