Support for Windows 7 is ending
All good things must come to an end, even Windows 7. After January 14, 2020, Microsoft will no longer provide security updates or support for PCs running Windows 7. But you can keep the good times rolling by moving to Windows 10.
Windows 7 systems will stop receiving patching after this date.
Your network will be at higher risk of attack if there are computers running Windows 7 on it after this date.
