However after explaining to users why running a machine with Admin is  
generally a bad idea (indeed, I don't run as Admin on my own box), I  
will inform of them of a machine(Non-AD) account that exists for  
admin, installs, etc "only." This machine account is a logged account  
which can be revoked as necessary.  This has worked well.  In the  
event that there is a program which needs admin to run on a regular  
basis - I can wade in with FileMon and RegMon as necessary. More often  
than not, the workarounds for any given SW title are already known and  
don't take a lot of resources to fix.

The thing that makes me nervous is the potential for weak credentials on that admin account. You're in a good spot 
compared to some of my institutions though, in that those accounts are one-off, and presumably have unique passwords 
for each of those accounts.

I find that after the WARNING spiel, users are usually happy to have  
access to an admin account even though in practice it is rarely  
required. On the other hand, there is always that one user who uses  
the admin account constantly and/or is a pain about having to switch  
accounts.  Since they tend to be more advanced users anyway, I'll give  
them full admin with the caveat that they'll get little to no support.

Have you explored if it would be sufficient to make that local administrative user non-interactive, letting your 
desktop user utilize the "run-as" functionality when running a software package or installer?

Cheers,
