Microsoft and Windows operating system

For Windows 10, we aim to make our future major product releases compatible with all Windows 10 releases that fit within a 30-month period, counting backward from the date of our product release. Regarding future compatibility, our products will receive Windows 10 compatibility updates while they are in Full Support, as defined in the previous chapter. At the end of the chapter, you can find a chart illustrating this principle in the context of our endpoint solutions. The relevant support chart is below.

Windows 11 release indicates a similar version convention used in the future as for Windows 10.

For earlier versions of Windows (8.1 and below), we are bound by existing commitments, and various exceptions have been granted to the rule. The table below clearly explains the compatibility matrix with existing products.

* Backward Compatibility - When an ESET product version is released, ESET guarantees compatibility of earlier operating system versions released within a specified period into the past. For example, Endpoint Version 8.x released during December 2020 is compatible with Windows 10 versions released up to 30 months earlier (June 2018) or since Windows 10 version 1803.

** Forward Compatibility - ESET guarantees compatibility of future operating system versions with the latest ESET product versions. For example, Endpoint Version 7.3 is compatible with Windows 10 version 20H2.
