Vispa is an open-source software that easily allows its user to tweak Windows Vista to disable all communication with Microsoft servers, increasing privacy and security, as well as improving the general performance. Do a few clicks rather than finding the write registry keys or program settings. However, you should not apply random settings without vague knowledge of what you're doing. Not every setting is desired in every environment. Vispa is no tool for beginners, just a more convenient way of tweaking your operating system.
