Full administrative rights

[Harry]

As the sole user of my home pc, I wish to have full administrative rights.
How do I do this?

Adding to Harry's post:

Being secure is nice and well, but:
due to the forementioned problem, i cannot delete a preinstalled trial
versions of an internet security system.
Because there is this new trial version installed i am not able to install
an older version that my company has user rights for.
so as normal administrator there is no way to uninstall the trial version of
the security software and therefore i cannot have security software???

This way I am for sure not more secure than without this UAC

I think this system is not optimal yet...
