I’ve gone through three four client logins at work and today I received a fifth but which didn’t have admin privileges on my local machine.  I called the help desk and had this conversation:

Tech Agent: What do you need admin access for?
Me: So I can control programs that were installed for all users.   I also need to make some registry changes.
Tech Agent: You seem to know what you’re talking about.  There are two ways to do this, first I could walk over and do the install.
Me: Or?
Tech Agent: I could just give you my username and password.  Just don’t tell anyone.
Me: Ok.

I can in no way see how me having a global admin login could be a problem and I consider this karma for getting a new login every darn time I return to work.
