Based on our Support Lifecycle Policy, product and security updates were no longer available as of July 11, 2017. As of October 11, 2017, users were no longer able to automatically or manually create new device backups for setting and some applications.

After December 16, 2019, the Store in Windows Phone 8.1 will no longer be available for downloading new apps or reinstalling previously downloaded apps.  Users who reset or reimage their phones will not be able to recover previously downloaded apps after this date.

Commercial Business

Windows Phone 8.1 was a great software release, but technology has evolved along with the needs and expectations of your customers and partners that have already adopted modern platforms and devices. An older mobile operating system can no longer address today’s business and technology needs nor security threats. Companies still on Windows Phone 8.1 are also missing out on tangible benefits of modernizing their IT investments and enhancing their security to meet the needs of a mobile workforce through future-proofing their IT investments.

Customers who do not want their users to upgrade their Windows Phone 8.1 device to Windows 10 Mobile should blacklist the Upgrade Advisor app using the MDM system of their choice. 

Windows Phone 8.1 end of support date is the same for consumer and enterprise. Microsoft encourages all of our customers with eligible phones to upgrade to Windows 10 Mobile.
