The maintenance dialog (Change/Repair/Remove) is a bit more convoluted.
We'd need to replace the radio-button selection with a three push-
buttons solution to make things easier. To make things worse, Change and
Repair don't seem to require elevation. Only Remove. This would make the
three push-button solution look ugly. Fortunately, not many people
wonder into the maintenance dialog. Therefore, we shall leave things
there as they are for the time being.
