Does Windows 11 26H2 require the Microsoft UEFI CA 2023 certificate?
Posted: Sat Oct 03, 2026 10:58 am
I'm still using BIU 2.03, since it does everything I need, but now the Windows 11 26H2 update pops up.
I assume BIU 2.03 still uses the Microsoft UEFI CA 2011 certificate. If Windows 11 26H2 would require the Microsoft UEFI CA 2023 certificate, then I assume installing the WIndows 11 26H2 update while still using BIU 2.03 will get me into trouble.
What should I do?
