About this tag
The extended security updates tag on WindowsForum.com covers Microsoft's paid post-support security servicing for Windows 10, Windows Server 2016, and Exchange Server. Discussions focus on the practical impact of end-of-support dates, such as Windows 10's October 14, 2025 cutoff and the extended patch availability through October 2027 for enrolled devices. Threads analyze market share data from StatCounter and Lansweeper, the cost and availability of ESUs for Windows 10 Enterprise LTSC 2021 and Windows Server 2016 via Azure Arc, and the necessity of ESUs for patching Exchange Server vulnerabilities like CVE-2026-62912. The tag emphasizes migration pressure, hardware upgrade barriers, and the operational decisions IT administrators face when support ends.

    Windows 10 ESU Costs Double in 2026 as Memory Shortages Reshape PC Refresh Plans

    Remember when a PC refresh was a calendar reminder? Every three or four years, the old laptops went out, a pallet of identical new ones came in, and the CFO groaned on schedule. A new ITPro feature argues that in 2026 the predictable routine is largely gone. In its place, organizations are...

    Windows 10 ESU Ends in 2027, Not 2028: Linux Mint 22.3 for TPM 1.2 PCs

    For a lot of Windows 10 owners, the TPM checkbox was where the upgrade path stopped. XDA Developers writer Simon Batt has published an account of what he did with a PC he describes as 12 to 13 years old.

    Windows 10 ESU Extends Security Updates Through October 2027

    SlashGear is right to flag the environmental pressure created by Windows 10’s end of support, but its “400 million PCs are now e-waste” framing overstates what the underlying evidence shows. Those machines did not become waste on October 14, 2025, when regular Windows 10 security servicing...
