It"s been nearly a year since support ended for Windows 10 version 1709 on Home and Pro SKUs. But while consumer versions of Windows 10 are supported for 18 months, some Enterprise and Education SKUs - including updates released in the fall and anything before version 1903 - get 30 months.
The Windows 10 Fall Creators Update was set to be retired completely on April 14, but with the end of life imminent, Microsoft is extending support for six months. This is due to the impact that the COVID-19 coronavirus is already having on businesses, and an attempt to not make it harder on them.
The new end of life date for Windows 10 Enterprise, Education, and IoT Enterprise will be October 13 for version 1709. In the blog post, Microsoft also suggested that organizations adopt Windows Update for Business, which will allow them to get updates faster.
With this extension of support, it"s worth noting that support for version 1803 ends just a month later. And since version 1903 uses the new 18-month timeframe for spring updates, that ends just a month after that in December.
