SANS ISC shares a friendly reminder, Microsoft will end Windows 7 support during JAN-2020

Not such a big deal if you have 1 or 2 machines at home to manage, but if you are an enterprise with hundreds or thousands of Windows 7 machines, it’s really time to start that migration project.  If you’re still running Windows XP, you’re in even deeper trouble!  If you’ve got business apps keeping you at W7 (or XP for that matter), it’s past time to consider an update or migration to better applications!  The difference I’m seeing between companies that run Windows 10 / Office 2016, and companies that run Windows 7 and older versions of office is a significant difference in rates of malware infection.

For folks still running Windows 7, Microsoft has it scheduled for End of Life in exactly 1 year
