From Jan T. Sott
xpy allows tweaking the default settings to your needs. This includes the disabling of services, changing the behavior and usability, deleting undesired files, or tweaking programs like Internet Explorer, Windows Media Player and Windows Messenger.
It is recommended to use xpy with care, it\'s not everybody\'s solution to make your Windows run better. Use it with care and it will help you making changes to your operating system much quicker.
Though xpy wasn\'t designed primarily to run of the mentioned Windows versions, you can also use it on Windows Vista. However, since the sister-product Vispa was specifically designed to run on Windows Vista (and Windows Server 2008), it\'s recommended to use it instead.
