The xp-AntiSpy is a little utility thatlets you disable some built-in update and authentication 'features' in WindowsXP.
xp-AntiSpy is a neat little utility to automatically apply different settings to the operating system, which could also be done by hand, but at a higher expense of time.
For example, there's a service running in the background which is called 'Automatic Updates'. I don't know what this service transfers from my machine to other machines on the internet, especially the MS ones. So I play it safe and disable such functions. If you like, you can even disable these functions manually, by going through the System and checking or unchecking some checkboxes. This will take you approximately half an hour. But why wast time when a little neat utility can do the same in 1 minute?
This utility was successfully tested by lots of users, and was found to disable all the known 'Suspicious' Functions in WindowsXP. It's customiseable, but comes up with the Default settings, which are recommended.

xp-AntiSpy will run on all Microsoft® Windows operating systems, because settings that do not exist, won't be shown.
