If you follow the Windows Embedded blog, you may have seen a similar posting about the Embedded Windows products. This is a shameless knock-off of that blog article re-purposed to cover the WEPOS and POSReady products…
What it is: Microsoft Support Lifecycle policy is the Microsoft standard for product support availability throughout a product’s life. Quoting the Lifecycle policy page: “By understanding the product support available, customers are better able to maximize the management of their IT investments and strategically plan for a successful IT future.” This is true for OEMs supporting POS devices as well.
Blog-worthy Embedded Windows Dates: The recent releases of Windows Embedded POSReady 2009 as the follow-on product to Windows Embedded for Point of Service, and Service Pack 3 for Windows Embedded for Point of Service, have initiated some support lifecycle updates that I thought would be of interest, and might become more meaningful with additional explanation.
Detailed (read: Lengthy) explanation: The following tables are based on the information found in each product’s Support Lifecycle listing.
In a nutshell Microsoft’s OS product Lifecycle policy is ten years; five years Mainstream support and five years Extended support. A variant to this equation is based on the follow-on product release timing. A product will have five years Mainstream support, or two years Mainstream support following the follow-on product’s General Availability Date, whichever period is longer.
For example, with the release of Windows Embedded POSReady 2009 as the follow-on product to Windows Embedded for Point of Service, the two year period of remaining Mainstream support for Windows Embedded for Point of Service commenced. When the Windows Embedded for Point of Service Mainstream support phase ends, the product will begin five years of Extended support. Review the Phases of the Support Lifecycle at the Lifecycle policy page.
A Service Pack is retired two years after the subsequent Service Pack is released, or it retires at the end of the product’s Support Lifecycle, whichever comes first. A non-retired Service Pack will be supported at the product’s current Lifecycle Phase, Mainstream or Extended, regardless of the age of that Service Pack. Learn more about Service Pack Support policy.
Okay, I’m going to wrap up – the complex logic has made my eyes cross just a bit, and it’s getting hard to focus on the computer screen. I hope this has provided some useful data, given you a clue as to how the data is determined, and that the scarce amount of levity has made it a bit more palatable.
Oh! A few afterthoughts:
