Today is the last day of support for Windows 8.1 systems as well as Windows RT 8.1 that does not have KB2919355 update installed. Microsoft announced this earlier this year. According to Microsoft, all systems running Windows 8.1 with automatic updates enabled should have this already installed.
If for some reason your Windows system didn’t install it – you can do it manually. Just download appropriate package for your system:
