I've been waiting for an update for this tool for well over a year. This is one if not the best tool for 'cleaning' the registry. I've been using it for over 2 years and it never gave me any problems. W2S did a good writeup of the tool last year as well. This update has been long in the making, but it's good that it's finally taking shape and form. Will give it a spin later tonight. =]

Unfortunately it's not free. But there is a 30-day trial and I bet subsequent betas can be used freely as well until the product reaches final production stages. It's still a solid app, I will definately be aquiring this one when it launches officially.
