Hello,
In Windows Vista, applications may not use your administrator power unless
you explicitly give them such permission (through a "Windows needs your
permission" screen).
Applications can either request admin permissions when they start, or, as is
the case with notepad, you will need to manually give it such permission.
Right-click notepad and click Run As Administrator - this will allow notepad
to use your full administrator powers.
