Yes, and I just re-did that, and I'm still getting the delay.  You did
notice that it's the plural version (Administrator_s_) that has the
delay -- Administrator (no 's') is just as fast as all the others.

Adding the '+' doesn't change the behaviour.

Ah, it occured to me to do an strace, and I found the culprit, I

Does that help?

Sorry, I am just a Un*x guy trying to live on a Windows box, I have
nothing like the necessary Windows sysadmin background to have an
opinion.  I thought I would try your snapshots precisely _because_ I
understand almost nothing about all this -- I followed the 'mkpasswd'
instructions 8 years ago, and never touched things after that, and I
was just trying to help by seeing if there was anything a trial by a
naive user could uncover before things got fully released.
