Instructions Regarding the SecureBoot Certificate for GEEKOM Devices

Updated on Mar,19, 2026

According to an official announcement from Microsoft, the legacy certificate used for Microsoft Secure Boot, which has been in place since 2011, will expire between June and October 2026. The expiration of this certificate may have certain implications for personal devices.

Situation	Impact Level	説明
Can the computer still boot normally?	Almost no impact	The computer can still start up, run programs, and access the internet normally after expiration
Daily use (office work, gaming, watching videos)	Basically no impact	Does not affect the browser, software, or files
Normal Windows updates	Most are possible	Regular security updates and feature updates can still be installed
Security protection during startup	Gradually decreases	Unable to receive new Boot Manager, Secure Boot database, or revocation list updates
Newly discovered bootkit/startup-level vulnerability fixes	Cannot be obtained	Security decreases over the long term (like an house’s防盗门 lock not being replaced, but the door can still be used)
BitLocker encrypted drives	May be affected	Some enhanced functions or new mitigation measures cannot be applied
Very rare special cases	Third-party startup items may fail	Such as certain older graphics card VBIOS, special dual-boot bootloaders

In the short term, there will be virtually no noticeable impact, but long-term security will be compromised—especially when new vulnerabilities emerge after the second half of 2026.

As shown in the figure, the method to enable the Secure Boot option in BIOS. On most devices, it is enabled by default and requires no manual configuration.

What Do You Need to Do as a Personal User?

1.Keep Windows Update enabled and install updates promptly

Settings → Windows Update → Advanced Options → Receive updates for other Microsoft products (turn on)
For most computers manufactured after 2020, the new 2023 certificate will be automatically pushed via regular cumulative updates in 2025–2026.

2.Check if the update has been applied

Open PowerShell as an administrator, then paste and run the following commands:

Check for the 2011 certificate:

([System.Text.Encoding]::ASCII.GetString((Get-SecureBootUEFI db).bytes) -match ‘Microsoft Windows Production PCA 2011’)

Check for the 2023 certificate:

([System.Text.Encoding]::ASCII.GetString((Get-SecureBootUEFI db).bytes) -match ‘Windows UEFI CA 2023’)

3.Check if the BIOS is Up to Date

According to information disclosed by the GEEKOM R&D department, as of March 19, 2026, the BIOS versions for the following models (and newer) already support the UEFI 2023 certificate. Updates for other models will also be completed before the UEFI 2011 security certificate expires.
