PlanSwift bases its Sunsetting Policy on Microsoft’s support for various versions of Windows. Microsoft has a two-stage retirement plan for its products. First is the end of "Mainstream" support, the second is the end of "Extended" support. See Windows Version Compatibility
Mainstream Support: When Microsoft officially ends "Mainstream" support for an operating system, we no longer test new products on that operating system. You can continue to use versions limited to these operating systems, however, our ability to provide technical support for those product versions is limited to licensing the product and providing basic troubleshooting assistance. Advanced technical support including defect reports, crash-troubleshooting, and installation issues are not supported for products limited to running on any version of Windows that has fallen off "Mainstream" support with Microsoft.
Extended Support: When Microsoft officially ends "Extended" support for an operating system, we consider versions limited to installation on that version of Windows (or earlier) retired. Products limited to operating systems that fall off Extended Support will no longer be longer distributed by PlanSwift nor will we provide technical support for them. This includes licensing, installation (including product downloads), and any issues, concerns, defects, or feature requests.
