Instant messaging services are popular for chatting online with your friends, and that's a known fact.

There are many heavy names in this market, and each one of them regularly invents some new features in order to beat the other ones.

Unfortunately, these companies often forget that not all users like sunshine and butterflies as their graphics, because they tend to consume more CPU and memory than usual.

For example, some users are perfectly happy with an older version of MSN Messenger or Windows Live Messenger.

But as soon as they try the latest version and find out they don't like it that much, those users are left with the impossibility of removing MSN Messenger or Windows Live Messenger to replace it with an older version.

This is why you should always have an utility software like ZapMessenger lying around the computer.

This application will remove any piece of MSN Messenger or Windows Live Messenger from your computer, enabling you to install any version over it.

How does ZapMessenger work? It first attempts to uninstall Messenger the traditional way, and if this fails, then it will use brute force to remove it from the Windows Installer engine.

What's not to love about a software that cleans up the mess left by others? It's easy to use, and you don't have to do anything, really, except pressing the Ok button.

ZapMessenger is certainly a most-have application for anyone who uses the instant messaging services from Microsoft, and who is not completely satisfied with the fresh version if offers.
