IMHO, a properly written product that changes something like that
will save the previous value somewhere so that it can be reset
when uninstalling the product.

Unfortunately too many software projects don't pay any attention to
uninstalling themselves.  It reminds me of the old Tom Lehrer song ``Once
the rockets go up, I don't care where they come down.  That's not my
department said Werner Von Braun''
