Administration authorisation

Anyone can help?
I have a problem to change the authorization to change/edit in Windows 7, system
(I am trying to install the wampserver, and I need to change the local host, which need a permission)
The Box which usually can be changed, was impossible to changed.

How I can changed this?

Thank you
