I have HP G61 laptop and I want to become an Administrator. I want to download Microsoft Windows Movie Maker to my desktop but whenever I try to, it comes up with the "Do you want the program to make the following changes to your computer?" and then it asks for a password to my mum or dad's account. If I get administrator rights, will I be able to put my own password in to download what I want? I'm really confused with the situation I'm in.
