My Pc has only one user, Vista Home Premium OS. I have knackered my system, here's how and why.
I unzipped a file and saved it to an ext. hdd, I then made a new folder and renamed it, then attempted 'drag+drop' of the file into new folder. I was not allowed without giving Permission. In an attempt to fix it I accessed ext. hdd properties>security tab and thats where I made 'errors' by interfering with things I did not understand.
What I need to know is what 'group or user names' should be on view and permission they should have.
