Windows 8.1 is set for release as a free update to current Windows 8 users on October 17th. Windows 8.1 is set to hit general availability on October 18th. But did you know that mainstream support for Windows 8.1 ends in 2018?
Those on Windows 8 will have two years to update to Windows 8.1, if they wish to be under the support lifecycle. Windows 8.1 users, on the other hand, will have Mainstream Support until 2018.
For those who like to be ‘in the know,’ Mainstream Support for Windows 8 ends January 9th of 2018. Mainstream Support covers paid support (per-incident, per hour, and others), security update support, non-security hotfix support, no-charge incident support, warranty claims, design changes and feature requests, product-specific information that is available by using the online Microsoft Knowledge Base, and product-specific information that is available by using the Support site at Microsoft Help and Support to find answers to technical questions.
Extended Support, which ends January 10 of 2023, covers everything listed above except you will not receive non-security hotfix support, no-charge incident support, warranty claims, or design changes and feature requests. Of course, those wishing to extend the “non-security hotfix support” can do so by purchasing an extended hotfix agreement, which must be purchased within 90 days of mainstream support ending.
On a side note, Surface Pro, which runs Windows 8 Pro, will receive the Windows 8.1 update on October 17th and will see Mainstream Support until July of 2017.
