Windows 8 users should upgrade to 8.1 [or 10]

This coming "Patch Tuesday", January 12, will represent the last batch of updates for Windows 8.   After that, it is considered End-of-Life, and no longer supported.   So any Win8 users should upgrade to [at least] Win 8.1... and if you wish, to Win 10.

Those still clinging to Windows Vista can count on more than a year of security updates, until April 11, 2017, and anyone running Windows 7 can do so with confidence until January 14, 2020.  Windows 8.1 reaches the end of its Extended Support phase on January 10, 2023.
