Some people are not too happy with the new Windows Live Suite that packs every software under a single installer and suggests changing your browser homepage / default search engine at the time of installation.
If you also prefer to download standalone MSI installers for different Windows Live products separately rather than the common installer, here are the links for all WL software:
Download Windows Live Writer wlwriter.exe
Download Windows Live Messenger wlmessenger.exe
Download Windows Live Toolbar wltoolbar.exe
Download Windows Live Photo Gallery wlphotogallery.exe
Download Windows Live Mail Desktop wlmail.exe
Disclaimer: I haven’t tried running the standalone Windows Live installers myself. The above download links were found in the WindowsUpdate.log file that exists in the default Windows Installation folder. Use at your own risk.
