Windows Live Messenger was switched off in most of the world in 2013
Microsoft's Windows Live Messenger will be switched off in China in October, marking a final end to the 15-year-old service.
Originally known as MSN Messenger, it was launched in 1999 but was switched off for most users in 2013, after Microsoft bought rival Skype.
Users in China continued to use the old service but will now be transferred to Skype by 31 October.
