About Windows Hardware Compatibility Program, is it necessary to re-certify the hardware if the BIOS version is updated?

According to AI answers, if the BIOS update does not do the following, re-certification is not needed.

  1. change the hardware ID such that it becomes another product
  2. support a newer Windows Version
  3. Drastically change certain functions like disable secure boot / TPM function

Is it true? Where can I find the official explanation or policy for this kind of scenario?

Thank you

Hi Alex,

I would not rely on those three AI-generated conditions as an official Microsoft rule. Microsoft’s WHCP documentation does not state that every BIOS version change automatically requires the entire system to be re-certified.

What matters is whether the updated product still meets the Windows Hardware Compatibility requirements applicable to its certification. If the BIOS change affects hardware behavior, security requirements such as Secure Boot/TPM, supported Windows versions, or anything covered by HLK testing, the updated configuration should be tested and may require a new or updated submission.

Microsoft also treats firmware packages distributed through Windows Update separately: those packages must pass the applicable HLK tests and be submitted through Partner Center for signing.

So a BIOS version-number change alone is not a reliable trigger; the nature and impact of the firmware change is what needs to be evaluated against the current WHCP policy.

Thank you, and feel free to respond back for more assistance.

Hi Alex,

A BIOS version change by itself does not appear in Microsoft’s published WHCP guidance as an automatic trigger for full re-certification. I also could not find an official Microsoft policy that states the three conditions you listed, so I would not treat those as formal rules.

The requirement is that the updated product continues to meet the applicable Windows Hardware Compatibility specifications and passes the required HLK testing. If the BIOS update changes functionality covered by those requirements, such as Secure Boot, TPM, ACPI, power management, or other platform behavior, re-testing and an updated submission may be necessary.

For a definitive decision on a particular BIOS change, I would check the WHCP Specifications and Policies for the Windows version being certified or raise the specific change with Windows Hardware/Partner Center support.

Thank you, and feel free to respond back for more assistance.
