Adminstration

I am a Vista Ulitmate user, and I am showing as the Administrator.

However if I try to transfer folders from one drive to another it says that
I have to be given admin rights? Also I have tried to install my service
providers internet access but again it comes up with I am not the
adminstrator?

One thing it is showing the PC as a work place not home, when I try to
change this to home it re-starts and still shows workplace.

Any guidance would be grateful.
