I Have Sony Vaio : SVF15A1ACXB and Pre-Installed Social Network - Chat App for facebook, Windows Messenger and Other Social Networking Sites - 'Messenger' App is Missing after Windows 8.1 Upgrade from Windows 8. I used Search on Windows Start Menu, But it Didn't Help.
There are instances that after a Windows 8.1 update some applications will be erased. What I can advise you is to just re-download and reinstall this apps from their respective websites or if it is available in the windows store you may do so. Hope everything works out.
