How to fix KMS Activation issue in Windows 7 after update

Microsoft recently made a change to its Activation and Validation Servers which caused Activation issue for the Windows 7 Professional and Enterprise users. Apart from Windows 7, other Microsoft products using the KMS activation service were also affected by the changes made.

Most Windows 7 users are seeing KMS activation issue post installing the latest security updates KB4480970 and KB4480960, but Microsoft confirmed that the activation issue is not related to the recent security updates.
