Microsoft Warns Unpatched Windows 11 PCs Face June 2026 Secure Boot Block
Secure Boot, a feature first launched in 2011 with Windows 8, included an initial wave of certificates that are set to expire starting on June 24th. We've covered this before, but Microsoft is renewing its warning with the deadline now less than a month away. While an expired Secure Boot certificate will not prevent the PC from functioning
Microsoft has started a transition to new Secure Boot certificates by June 2026 to replace obsolete standards dating back to 2011. Redmond insists that this critical change is necessary to address a number of issues. If users ignore this update, their PCs will continue to work, but their security will be compromised, as they will no longer receive critical fixes for booting. This technical process is done in stages via e-mail.
At one month of the expiration of the first historical Secure Boot certificates, Microsoft removes the suddenly unusable Windows 11 PC scenario. Late machines will continue to start, but their boot security risks gradually dropping.
The current Secure Boot certificates will expire next June, threatening users who will not be able to update the safe launch.
