I don't get it... people are seriously recommending installing a third party utility that hacks your registry, as a more secure alternative to simply hacking it yourself?
Maybe GWX Control Panel is completely benign and does exactly what it says on the tin. And maybe it will continue to be so through all future updates. But even in this best of all possible cases - for the most clueless user that you remotely care about, is this really the precedent you want them to take on board?
