Computers running Windows 8 will not get application or operating system and security updates after July 1, 2019. If you have Windows 8 you can upgrade to for free to Windows 8.1 or move on to Windows 10. Windows 8.1 devices are scheduled to get application updates through July 1, 2023. This is from the following Neowin article:
“Last year, Microsoft announced when it would be killing app updates and distribution in the Windows Store for Windows Phone 8.x and Windows 8.x. At the time, the blog post stated that Windows Phone 8.x devices would stop receiving app updates after July 1, 2019, while Windows 8.x devices would get app updates through July 1, 2023.
However, it seems as though plans have changed a little bit, as the blog post has quietly been updated earlier this month. As spotted by Nawzil on Twitter, Microsoft has changed the wording in the post to state that Windows 8 devices will stop getting updates for their apps at the same time as Windows Phone 8.x, that is, July 1 of this year. Windows 8.1 devices will continue to receive updates through the previously announced date in 2023.”
