Good old MSN Messenger, now known as Windows Live Messenger, has recently turned ten, and Microsoft is celebrating this first decade with a special pack.
The Windows Live Messenger 10th Anniversary Pack is a collection of winks, backgrounds, avatars and emoticons with which you can spice up your chats and join the celebrations for Messenger's birthday.
The pack is a bit scarce for my taste, but at least is easy to install. Simply double click the EXE file and make sure your Windows Live Messenger is already running. Just be aware that the installation process will offer to turn your default search engine to Bing and make MSN your homepage, so if you don't want that to happen, uncheck the relevant boxes.
The Windows Live Messenger 10th Anniversary Pack includes everything you need to celebrate Messenger's anniversary – though in a quite austere way.
