Microsoft ending support
Microsoft announced that they will end support for Windows 7 on January 14, 2020 and will no longer provide security updates or technical support for systems running Windows 7 after January 14. You can find more information about this announcement on Microsoft's website.
Why is it important to update?
Working on Windows 7 past January 14, 2020 increases your security risks, degrades performance, and leaves your firm vulnerable to attack and exploitation. Upgrading your workstation(s) safeguards you and your client data.
