We assess the state of public health and understand the impact it has on you, our valued customers. To facilitate one of the many charges you face and based on customer feedback, we have decided to delay the scheduled expiration date for Enterprise, Education and IoT Enterprise versions of Windows 10, of the issue 1709. This means that devices will only receive monthly security updates from May through October. The final security update for these versions of Windows 10, of the issue 1709 will be released on October 13, 2020 instead of April 14, 2020.
