Microsoft has "bundled" some of the most popular online services together in one installer to make deployment much easier. Among these services is one of my personal favorites, and that is
Windows Live Writer. It makes it easy to create and publish blog posts to several sites including WordPress.
"Today
we’re releasing beta versions of a new generation of Windows Live
software designed for your Windows PC that makes it easier than ever to
get connected to Windows Live or other services. This suite of software
includes e-mail (Windows Live Mail), photo sharing (Windows Live Photo Gallery), a great publishing tool that lets you post directly to your blog (Windows Live Writer), parental controls (Windows Live OneCare Family Safety), a new version of Windows Live Messenger (8.5), and more.
Starting today, you’ll be able to install the entire suite of
these downloadable Windows Live services at one time, from one place,
instead of going through separate installations for each service. Of
course, if you don’t want the entire suite, you can still get each
application individually."
