Disable admin approval mode in Vista home premium

My new computer came with Vista home premium and all I want to do is get into
some folders that I'm locked out of even though I'm set to admin. It seems
Admin doesn't mean what it use to in Vista. I have found instructions to use
secpol.msc but that policy doesn't exist in the home version. I desprately
need a hack or someway to disable the admin approval mode. I sure hope
someone has a way and they will share it with me. I'm flabber gasted the MS
would lock us out of our own computer.
