Changing account type - changing GUI and desktop customizations, too?

[OvenMaster]

I originally made one account with admin rights on my PC in June.

I added a standard account for my dad last week, but the only way I could customize the desktop and theme for him with larger fonts, non-Aero theme, fewer desktop icons, etc was to make his account an admin account also. Otherwise when I tried to open the Control Panel to customize things, I only got error messages saying stuff along the lines of "this page was unable to load". I also had broken shortcut images (generic Windows icons, no arrows) until I made it an admin account.

Now that I've made all the customizations I want to his desktop and theme, will removing admin rights and downgrading his account to a standard one screw up the customizations? Can I switch it back and forth if I wish to make additional changes or customizations in the future?

Okay, I guess I can answer my own question.

Switching an Administrator account to a Standard account does screw up icons in Computer - it makes them vanish, actually - but not those on the Desktop.
