If you agree the question is badly answered or voted, and you've acknowledged that the answer containing regedit code is the right one, why haven't you voted it up yet?
Ever since joining Super User, a year and seven months ago, you've only voted 9 times – but voting is the essential way of letting others know what's useful and what is not, so please exercise your right to do so and vote more. You can vote as much as 30 times per day, and 10 times more on questions.
If you want to draw more attention to an answer, you can also place a bounty on the question and reward the existing answer. There's a dedicated bounty reason for that purpose.
