Vista - How to give Full Control to new user

Hi everyone:

My laptop has Windows Vista Home Basic. The laptop has one user only, by
default it should be given Full Control and Modify to the user when Vista was
installed. But the only user on the laptop does not have permissions in Full
Control and Modify and it could not be added as the check boxes for these two
were grayed and nothing could be done.

The only user logged in and under Security, it was shown Administrators
(my-PC\Administrator). In the same list, SYSTEM has all checked box ticked.

This might have caused me some troubles to run my application raised in my
other thread.

Can anyone give me some advice how to solve this problem?


Thank you in advance.


Cheers,

Ke
