While doing some sort of "bisecting" for bug #55407 I saw the following in
Windows 7:
(* I needed to install Octave as "Administrator" as I installed "for all
users". Just a pop-up requesting to enter the Administrator password just
like on *nix)
* In the end the uninstaller asks to remove some files upon next reboot - I
clicked "No" each time
* Then, in the explorer (file browser) I could simply delete the remnants of
Octave's installation directory as a normal user.

In conclusion, after uninstalling there's nothing holding the remaining
files locked, it seems as if it's just the uninstaller process that cannot
jump through its own hoops.
I didn't check if the "remove on next reboot" option really works.
