There are still many folks out there standing by Windows 7… If you are one of those people, it is important (actually critical) that you get the next Windows 7 update. Also, as a further note, support for Windows 7 is set to end on Jan 14. 2020
If you want to continue receiving Windows updates, then the next Windows 7 and Windows Server 2008 update is critical as it adds support for SHA-2 encryption. Without it, future updates can’t be downloaded.
