Security update for our Yahoo! Messenger for Windows (8.1) users. Due to restrictions with the Windows Vista operating system, we were unable to push the update out to our Vista users on Yahoo! Messenger 8.1.
We encourage all Yahoo! Messenger 8.1 users running Windows Vista to download and install this security patch, available at http://messenger.yahoo.com/updater.php.
The updater page also includes information on how to check your version of Yahoo! Messenger. If you’re on Yahoo! Messenger version 18.104.22.1681 or higher, you don’t need to install this additional patch.
