Windows 10 version 22H2 is an operating system version, not a BIOS/UEFI firmware version. BIOS (or UEFI) updates are separate from Windows feature updates and are not labeled as “22H2.” Any statement that “the Microsoft Windows BIOS version must be updated because 22H2 is deprecated” is mixing up OS lifecycle status with firmware.
Key points for this scenario:
- Windows 10 22H2 deprecation and security updates
- Windows 10 support (including 22H2) ends on October 14, 2025. After that date, Windows 10 no longer receives free security updates, technical assistance, or security fixes from Microsoft.
- Until that end-of-support date, Windows 10 22H2 continues to receive cumulative and security updates (for example, KB5065429 in September 2025 and KB5066791 in October 2025).
- These updates are OS-level and do not represent BIOS versions.
- BIOS/UEFI vs. Windows version
- Firmware (BIOS/UEFI) on Surface and other devices is provided as separate firmware updates, typically delivered via Windows Update under “firmware” or “Surface” categories.
- Firmware versions do not use Windows feature labels such as “21H2” or “22H2.” Therefore, a “BIOS 22H2” requirement does not exist in the provided information.
- Surface firmware and configuration
- On Surface devices, firmware features such as Secure Boot and TPM are managed in BIOS/UEFI, but these are independent of the Windows 10 22H2 lifecycle.
- Access to BIOS/UEFI on supported Surface models is done at startup (for example, by using hardware buttons as documented for earlier Surface Pro devices), and changes there affect security features, not OS support dates.
- Interpreting the “pushback” on BIOS update
- If a device is already running Windows 10 22H2 and is still within support (before October 14, 2025), it can continue to install security updates without any special BIOS version requirement indicated in the context.
- Any recurring message or process that appears to “push back” on a BIOS update while citing Windows 10 22H2 deprecation is likely misinterpreting the OS end-of-support notice as a firmware requirement.
- Recommended handling
- Ensure all available Windows Updates are installed, including any offered firmware/Surface updates, while Windows 10 is still supported.
- Plan to move the device to Windows 11 on supported hardware because Windows 10 support ends on October 14, 2025.
- Treat references to a “Windows BIOS 22H2” as an incorrect conflation of OS versioning with firmware; there is no BIOS update dependency for 22H2 deprecation in the provided material.
