Product Lifecycle Guidelines:
Microsoft® Windows® Desktop Product Lifecycle Guidelines provide advanced notification of planned changes in Windows desktop operating system availability and support. This information will assist customers and partners with product planning and information technology decisions. Under the Product Lifecycle Guidelines, Microsoft plans to make Windows desktop operating system licenses available for purchase for a minimum of five years and assisted support offerings available for four years. However, during these periods, Windows desktop product availability and assisted support will move through the Product Lifecycle Phases identified below.
--------------------------------------------------------------------------------
Product Lifecycle Phases:
Mainstream Phase: Three years after general availability.
Licenses available in all standard product distribution channels (e.g. direct OEM, authorized OEM distributors, retail, and Volume Licensing programs via licenses or via downgrade rights*).
Standard support offerings available (e.g. Premier Support, incident support (per warranty), hotfix support**, online support information, etc.).
Extended Phase: Between three and four years after general availability.
Licenses only available in the authorized OEM distribution channel and through downgrade rights available in Volume Licensing programs*.
In addition to Premier Support, paid incident support, paid hotfix support**, and online support information will be available.
Non-Supported Phase: After four years of general availability.
Licenses will continue to be available in the authorized OEM distribution channel and through downgrade rights available in Volume Licensing programs*.
Online support information will continue to be available.
