Okay, now we all know about the 'Coolbits' registry tweak that enables
the clock frequency adjustments on nvidia cards, right ? Problem is,
on Windows XP, it only works if you log in with an 'Administrator'
account. This is what I can do :

(1) Log in with an 'administrator' account.

(2) Change the clock freq. of the graphic card.

(3) Set it to automatically change every time I log in.

Thereafter, every time I log in with that account, the card's clocks
are automatically reset to the values I want.

Currently, the clocks only reset if I log in with an 'administrator'
account. I want to do this when I'm logged in with a 'limited'
account.

I can work around this by logging in to an administrator account, and
then logging off and logging on to the limited account, but that is
not what I want. I want to be able to log in directly to a limited
account and have the graphic card clocks reset to my preferred values.
Operating system is Windows XP Professional (SP1, all patches in) and
Asus V8420 (GF4 Ti4200). Drivers are NVidia reference version 40.72.
