Jura, on the Windows Live Messenger Team, just posted an entry on the team's blog summarizing upcoming 8.5 client pushes to consumers around the world. Okay, in itself this isn't very interesting but what caught my eye was this white lie:
"A special note for those of you running Messenger 8.5 Beta on Windows XP 64-bit or Windows 2003 Server: the final version of Messenger 8.5 will not install or run on your OS"
BZZT. Wrong, sorry. Thanks for playing. Windows Live Messenger works fine on all architectures of Windows XP and Windows Server 2003, just download the MSI and install.
I hate FUD.
Update: Jonathan Kay has petitioned Microsoft to remove the claims and host the MSI file. I couldn't agree more.
