I do agree that Beta softwares have very limited support and can even corrupt your system. But little did I ever imagine that Microsoft would ship out a Beta release of Windows Live Messenger without an Uninstaller!! Yes - the latest Windows Live Messenger 2009 Beta comes without an UnInstaller.For some strange reason, after installing the Windows Live Messenger 2009 Beta - I was getting an error called 8000ffff - I tried many solutions posted online but in vain. Finally, I felt my Messenger 8.1 was much better and there my hunt for the uninstaller began. I searched high and low but in vain.
Finally, I found an easy method to Uninstall Windows Live Messenger 2009 Beta. Goto Start > Run and type the following command and press enter - this starts the uninstaller.
msiexec /x {B1403D7D-C725-4858-AACC-7E5FA2D72859}How funny?
Btw, for the other Live Beta softwares - here are the codes to uninstall.
