Upcoming Microsoft Certificate Expiration in June 2026 – Impact on Start9 OS?

General

Hi everyone,

I’m running Start9 OS on a Lenovo M910q and recently came across information that Microsoft certificates will expire in June 2026. From what I understand, this could affect computers worldwide — potentially preventing them from booting unless updates are released in time or Secure Boot is disabled.

My questions are:

  • Do I need to manually renew these certificates when running Start9 OS, or is this unnecessary?
  • Would simply disabling Secure Boot now be a safe workaround?
  • Has anyone already looked into how Start9 OS will handle this situation?

Thanks in advance for any insights!

Certainly wouldn’t affect computers worldwide, it would only affect those people unfortunate enough to use Windows with Secure Boot with the underlying compromised UEFI. Server Pure users would be unaffected.

If you installed StartOS on this Lenovo, you probably disabled Secure Boot to get it to work properly and can simply do so now if you didn’t, and/or you could do so in 2026 if needed.

While not on anyone’s radar yet, it may be something to take into consideration in the new year.
