"Oye, cabron," I started,  "You wanna disable all that UAC stuff?"

After making him beg me for a while, I told him how to do it.  In summary here's what you do:

• Start an elevated command prompt window, and from that window run secpol.msc.
  


• Find all the policies that start with "User Account Control" (there are only, like, six of them) and set them to either no prompt or disabled.

That's all there is to it.  You'll never need to "run elevated" and you'll never be bothered by those pop-ups again.

Of course, I let him think I used some super-secret inside knowledge that I picked-up in the halls in Redmond.  But, actually, I learned this in a blog by some dudes on the UAC team: http://blogs.msdn.com/uac/archive/2006/01/22/516066.aspx.  The blog explains each of the options, in case you want to be a bit more subtle (and secure) than taking the sledgehammer approach and shutting everything off.
