Win7Zilla

Looking to tweak and customize just about any part of Windows 7? Win7Zilla will let you change an astonishing number of Windows 7 features. Not only does it let you change just about any part of the operating system, but in many instances it also shows you exactly what each adjustment will do, which is rare in a system tweaker.

Win7Zilla puts you in charge of almost every part of the operating system, with an incredible amount of fine-grained control. On the Start menu alone, for instance, you can perform more than two dozen tweaks. Now imagine having that level of control over virtually every aspect of Windows 7, from the desktop to the Control Panel to security settings, as well as to Internet Explorer, Windows Explorer, and beyond. You also get other practical tools, such as a file cleaner and a Registry cleaner.

What really sets Win7Zilla apart is how clearly it explains the effects of your changes. It provides succinct descriptions in plain English--but better yet, it also shows you screenshots, so you can see what will happen. No other tweak utility does this.

If you're willing to pay for a Windows 7 tweaker, you won't do better than this one.
