I need to remove some files. I try but am denied as I don't have administrative rights. How do I get them? I m the only one to have ever used the laptop. It was bought brand new. I've run Windows since 3.1 but only with 7 have I been asked this. Is this a new feature? What's the purpose? I was thinking stolen software or computer, but with hackers and crackers around, can't the rights be reset or reassigned?
