Eh, not sure what that means.
This admin approval policy existed before, but in Vista and 7 it was disabled when you put UAC at minimum settings. With 8, minimum UAC settings keeps this policy enabled. If you disable the policy explicitly, metro apps will bitch about UAC being disabled and will refuse to start.
If you keep the policy enabled and enter "subst M: C:\SomeFolder\" in an Admin command prompt and then go to M:\ in windows explorer, windows will return an error about M:\ not existing. But if you do the same thing in a non-admin command prompt, it will exist. The problem with this is that I use batch files that are invoked by admin programs, and other programs that depend on that subst working in windows explorer. I think the concept of an Admin user account not being actual Admin really non-intuitive and not very useful. So for now, I simply don't use metro apps until someone figures out how to correct this design flaw.
See the post starting with "Okay, here we go" to see how this policy impacts windows explorer in other ways

Basically Microsoft made UAC mandatory.
Can't you just establish the subst in both command prompts?
