Tweaking the registry in Windows is one of the best ways to customize Windows in ways that are not widely available. The one problem with it is that many of the customizations are obscure. And even worse, you can seriously mess up your computer if you somehow screw up the editing and invalidate your registry.

If you want the power and customization of registry editing without the worry of messing up your computer, there's an app called TweakNow that makes it easier. It allows you to perform many of the customizations available in the registry editor without having to actually touch the registry editor, so the risk of messing things up is gone. If you want to ultra-customize your Windows computer safely, this is the easiest way.
