The scripts used to install Erlang on windows are available here:
https://github.com/erlang/otp/tree/master/erts/etc/win32/nsis

You should be able to see from there what things are changed when it is
installed and revert them.

I don't know how well the installer handles roll-backs, but I would imagine
that it could be problematic.
