Interesting and surprising. I guess you've concluded that my 
testing/reporting was from an admin account. Not only did I not get a 
request for an admin password, I did not get a confirmation dialog that 
I should proceed with admin access (like happens with installing 
programs, and running .reg files).

Interesting and surprising again.  User variables for the admin account, 
or user variables for the user account, once you achieve admin access.  
Perhaps the only way to discover the difference would be to create a 
new, junk variable when you get the dialog, and then reboot, and login 
as that user, and see if the variable persisted in user mode (can be 
seen by starting a CMD prompt, and doing set command).

This seems extremely limiting.  User variables should be for the user, 
not the admin, and should be able to be set/saved by the user without 
having admin access. I wonder in what version of Windows this limitation 
was introduced... it is ridiculous, especially when people are preaching 
that you shouldn't need to run as admin all the time, for better 
security in Windows.
