Today is there day when Windows 7 reaches End of Life (EOL), this means that Microsoft won’t provide any further updates so should a security issue be uncovered, it will be left open for hackers to exploit. It is therefore strongly recommended that if you do use Windows 7, you should upgrade to Windows 10 ASAP.
Combined with that, there are currently reports out that a major flaw has been found within Windows 10 and Windows Server 2016 relating potentially to cryptography / security certificates. We have now rolled out this patched to all impacted servers.
