xp-AntiSpy is a small utility that lets you disable some built-in update and authentication features in Windows XP.

For example, there's a service running in the background which is called 'Automatic Updates.' And you don't know what this service transfers from your machine to other online machines, especially the MS ones. So, 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 waste 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 customizable, but comes up with the Default settings, which are recommended.

This utility is DONATIONWARE! This means you don't have to pay anything for this program; you can give it to anyone interested in it as long as you don't sell it. If you find this tool useful and want to give something back, consider donating a small amount of money to the author.
