Microsoft is ending support for mobile push notifications on its Windows Phone 7 and 8 software by February 20th. Devices on Windows Phone 7.5 and 8.0 will no longer receive notifications. They will also lose the useful live tile updates that displayed information at a glance, and users will no longer be able to locate devices with the “find my phone” feature. Those phones were initially released to the public in 2011 and 2012, respectively.

It’s yet another nail in the coffin for Windows Phone. Microsoft announced in October that it would stop developing new features or hardware for Windows 10 Mobile. Even before Microsoft admitted it, the mobile operating system had pretty much been dead for a year, as it showed dismal market share numbers through 2016 and plummeted to a mere 0.1 percent of the market by Q1 of 2017, according to IDC.

The Microsoft announcement stated, “Windows Phone 7.5 and Windows Phone 8.0 have reached their end of support dates, and thus services for these versions of Windows will be discontinued over time.” Meanwhile, newer phones running Windows 10 Mobile are still fully supported, and Windows Phone 8.1 can still receive notifications.
