After used Windows 8 for a period, I found that my account's permission is not the administrator's permission. sometimes I wanna modify something in C drive, it will tell me that I have no administrator's permission.
However, this account is the only one when I install Windows 8. How possible that it is not administrator?
I can not understand default settings of Microsoft Windows 8 now. And I need full permission of Windows 8. How can I get that?
