TL;DR
For end of support October 2026, endoflife.date's October 14, 2026 reading lists a phase ending on October 13, 2026 for Microsoft Office 2021, Windows 10 1607 (E) (LTS), Windows 11 24H2 (W), Windows Server 2012, Windows Server 2012 R2 and Windows Server 2022 (LTSC). Each date closes one named phase only, and where the source lists no later phase we say so rather than assume support continues. No Apple, FortiOS, SQL Server, VMware or Veeam phase on our list ends within the month.
- Phases ending October 13, 2026: Office 2021, Windows 10 1607 (E) (LTS), Windows 11 24H2 (W), Windows Server 2012, 2012 R2 and 2022 (LTSC).
- Microsoft Exchange 2016 CU23 SU19 and 2019 CU15 SU5 Extended Security Updates end November 1, 2026.
- Apple iOS 26 and macOS 14 (Sonoma) phases ended September 14, 2026; FortiOS 7.2 End of Support ended September 30, 2026.
- Every date is endoflife.date's, so confirm it on the vendor's own lifecycle page before acting.
What reaches end of support in October 2026?
Our October 14, 2026 reading of endoflife.date, a community-maintained project that compiles vendors' published lifecycle dates, covers all 15 products we track. Phases for Microsoft Office, Windows and Windows Server products, and nothing else on our list, end on October 13, 2026. We counted dates from the reading day, so these phases had already ended when we read them.
endoflife.date lists Microsoft Office 2021 Active Support and Security Support as ending on October 13, 2026.
The same reading lists Windows 10 1607 (E) (LTS) Security Support, Windows 11 24H2 (W) Active Support and Security Support, Windows Server 2012 and Windows Server 2012 R2 Extended Security Updates, and Windows Server 2022 (LTSC) Active Support on that date. Each entry names one phase. A product can have other phases with other dates, or none listed.
What do these Microsoft phase names mean for each version?
Each date closes only the phase the source names; it is not a statement about every phase of the version. Windows Server 2022 (LTSC) is a clear case: this reading carries its Active Support date and nothing further, and this sheet carries no later phase date for it, so we cannot say what happens afterward.
The lettered editions of Windows 11 24H2 also differ. The (W) cycle shows October 13, 2026, while Microsoft Windows 11 24H2 (E) shows Active Support and Security Support ending October 12, 2027. We use the labels exactly as the source prints them and do not expand them.
endoflife.date lists Windows Server 2012 and 2012 R2 Extended Security Updates as ending October 13, 2026.
Microsoft's own Windows Server lifecycle page may not show Extended Security Updates dates, so that date is endoflife.date's and worth confirming with Microsoft directly.
Do Apple, firewall, SQL Server, VMware or backup phases end this month?
No. Of those families, nothing on our list ends in October 2026; the nearest dates fall just before or well after it. Apple iOS 26 Active Support and macOS 14 (Sonoma) Service Status ended September 14, 2026, and FortiOS 7.2 End of Support ended September 30, 2026. The source cites no vendor lifecycle page for Apple or FortiOS, so we have no vendor page to point you to for those dates.
Microsoft Exchange 2016 CU23 SU19 and 2019 CU15 SU5 Extended Security Updates end November 1, 2026, as of the October 14, 2026 reading. SQL Server dates start later: 2014 'Hekaton' SP3 Extended Security Updates on July 12, 2027 and 2017 'Helsinki' Security Support on October 12, 2027. VMware ESXi 8.0 and vCenter Server 8.0 General Support end October 11, 2027.
endoflife.date lists Veeam Backup & Replication 12 End of support as February 28, 2027.
Firewall dates sit in the same later window: Palo Alto Networks PAN-OS 11.2 and 11.1 on May 2, 2027 and May 3, 2027, and FortiOS 7.4 End of Engineering Support on May 11, 2027.
How should Chicago buyers read these dates?
Read them as a prompt to check, not a verdict. Any date should be confirmed on the vendor's own page, such as Microsoft's Windows lifecycle page, before anyone acts on it. A date can also change after our October 14, 2026 reading.
Freshness varies by product. The source last changed its Microsoft Office entry on May 1, 2026 but changed Exchange and Veeam on October 10, 2026. Coverage is wide but not complete: as of our reading the Windows entry lists 49 cycles, 16 with some support left, and Windows Server lists 20 cycles, 6 with some support left. Check whether the versions on your own network appear in the source at all.
Software end of support dates are one input. They do not tell you which versions your own environment runs. If you are building that inventory before engaging a provider, our guide to pre-engagement IT assessments covers the wider picture. This publication is owned by a Chicago Managed Service Provider (MSP) that is itself ranked on our site, so we have a commercial stake in IT subjects, and nothing on this page is a reason to choose or avoid any provider.
What does the full end of support calendar look like?
On our list it runs from September 14, 2026 to October 12, 2027, as of endoflife.date's October 14, 2026 reading. Phase names are the source's own and are not interchangeable across vendors, so compare dates only within the same phase name.
endoflife.date lists Palo Alto Networks PAN-OS 11.2 End-of-life Date as May 2, 2027, a date Palo Alto Networks' end-of-life summary is the place to confirm.

Frequently asked questions
Did any support phase end in October 2026?
Yes. As of endoflife.date's October 14, 2026 reading, phases for Microsoft Office 2021, Windows 10 1607 (E) (LTS), Windows 11 24H2 (W), Windows Server 2012, Windows Server 2012 R2 and Windows Server 2022 (LTSC) ended on October 13, 2026. Each is one named phase.
Does the end of one phase mean all support is over?
No. Each date closes only the phase the source names, such as Active Support or Extended Security Updates. Where the source lists no later phase, we say it lists none rather than saying support continues.
What is the next Microsoft date after October 13, 2026?
Microsoft Exchange 2016 CU23 SU19 and 2019 CU15 SU5 Extended Security Updates end November 1, 2026, per endoflife.date. Microsoft Windows 11 23H2 (E) Active Support and Security Support follows on November 10, 2026.
Where do these dates come from?
Every date is as endoflife.date lists it, not as a vendor states it. Confirm any date on the vendor's lifecycle page, which may not show every phase, before acting on it.
