End of Life Data for Microsoft Windows
A normal EOL entry for Microsoft Windows (in this case for Server 2012) looks as follows:
Product Version | ESU Applied | Start Date -> GA Date | Mainstream End Date -> Retirement Date | Extended End Date [Top table] OR End Date [Bottom table] -> End of Support Date | End of Security Support Date | Extended Security Update Year 3 -> End of Extended Support Date |
|---|---|---|---|---|---|---|
Server 2012 | This EOL entry assumes we are unable to ascertain if the customer has purchased any extended support from Microsoft following the final service pack in the form of an ESU subscription | 2012-10-30 | 2018-10-09 | 2023-10-10 | N/A | 2026-10-13 This date being the EOL date for the ESU subscription with the maximum number of years (i.e 3) that may be purchased from Microsoft for additional monies. |
For certain operating systems, an attempt is made to ascertain if the customer has purchased an ESU subscription from Microsoft, whereby the EOL data provided can be more targeted and reflect the true End of Life dates:
Product Version | ESU Applied | Start Date -> GA Date | Mainstream End Date -> Retirement Date | Extended End Date [Top table] OR End Date [Bottom table] -> End of Support Date | Extended Security Update Year X -> End of Security Support Date | Extended Security Update Year 3 -> End of Extended Support Date |
|---|---|---|---|---|---|---|
Server 2012 | ESU Year 1 | 2023-10-11 This is the day following the End of Support date | 2018-10-09 | 2023-10-10 | 2024-10-08 As you have purchased a 1 year ESU subscription, this date appears here as it relates to security support beyond the normal End of Support date | 2026-10-13 This date reflects that fact that you can pay additional monies to Microsoft to increase your current ESU subscription from one year to three years |
ESU Year 2 | 2024-10-09 | 2018-10-09 | 2023-10-10 | 2025-10-14 As you have purchased a 2 year ESU subscription, this date appears here as it relates to security support beyond the normal End of Support date | 2026-10-13 This date reflects that fact that you can pay additional monies to Microsoft to increase your current ESU subscription from two years to three years | |
ESU Year 3 | 2025-10-15 | 2018-10-09 | 2023-10-10 | 2026-10-13 As you have purchased a 3 year ESU subscription, this date appears here as it relates to security support beyond the normal End of Support date | No date will appear here as you have already purchased the maximum number of years of ESU support |
