Microsoft outlines Windows 10 deprecation strategy for WHCP and HLK

Upcoming Changes to Windows 10 Support and Certification

As of October 14, 2025, support for Windows 10 will officially end, following its last set of non-security updates. Users in Europe can benefit from the Extended Security Updates (ESU) program without conditions, while other regions may have specific limitations. This marks a definitive closure for Windows 10, prompting significant shifts in Microsoft’s policies regarding hardware compatibility.

Microsoft’s Windows Hardware Compatibility Program (WHCP)

The Windows Hardware Compatibility Program (WHCP) is a critical initiative for hardware manufacturers. It facilitates the testing of device compatibility with Windows prior to their market release. Within this framework, the Windows Hardware Lab Kit (HLK) provides an automated testing environment for drivers, ensuring devices that pass the testing process are certified by Microsoft. This certification not only boosts the credibility of the products but also enhances consumer trust.

Deprecation of Windows 10 Certification

Post-October 14, Microsoft will discontinue the certification process for Windows 10 within the WHCP, with a few exceptions. The Windows 10 LTSC 2021 (22H2) and HLK 22H2 will remain eligible for support until 2028, as part of the ESU program, which offers paid security updates for enterprise users for up to three years. For Windows Server systems, the HLK versions 1809 and 22H2 will continue their role in aiding Windows Server LTSC releases until they also reach their end-of-life (EOL) indicators. It’s crucial to highlight that, commencing January 2026, Microsoft Premier Support will cease to accept submissions for obsolete HLK versions.

Impact on the Hardware Dev Center (HDC)

The Hardware Dev Center (HDC) serves as the key portal where hardware manufacturers submit drivers for compatibility testing. Currently, it will maintain the acceptance of HLK packages for all Windows 10 versions. However, Microsoft has not yet disclosed specific timelines related to the discontinuation of unsupported HLK submissions within the HDC. Nevertheless, the company has strongly urged partners to transition to supported HLK versions without delay.

Conclusion

With the impending end of support for Windows 10, hardware manufacturers must swiftly adapt their strategies and ensure compliance with the updated WHCP and HLK practices. The continuation of support for certain versions provides a temporary safety net, but manufacturers are encouraged to pivot towards contemporary frameworks to enhance product longevity and user satisfaction.
