I agree. I'll work this up before alpha 1. (FWIW, it defaults to unselected.)

Displaying a warning about other Pythons already being on the path at this point is trickier, but I can probably figure something out.

Inclined to agree, and it is possible to make the default on the customise page switch with the Install as Administrator checkbox until it's been manually edited. My main concern is people who want it the old way, but they may not actually exist. Perhaps making the old way trickier is the best way to flush them out sooner...
