Microsoft is updating Secure Boot certificates for Windows 11 PCs, as the previous certificates are 15 years old and nearing expiration. Users can check their certificate status easily. An advisory was issued in early September regarding changes for Windows Insider channels, particularly affecting the Experimental and Beta channels, with a deadline for certificate updates set for August 11, 2026. The Release Preview builds will not be affected by this update requirement. Users in the impacted channels must update to specific builds to obtain the new certificates, or they may stop receiving updates after the deadline. The minimum build requirements for each channel are outlined, and users can check their current Windows 11 Insider build by using the winver command. Microsoft has confirmed that these updates will not impact activation or licensing status.
