Older systems may need manual updates.<\/li>\n<li>These instructions help you to check certificate details and manually install 2023 certificates.<\/li>\n<\/ul>\n<p>On <a href=\"https:\/\/pureinfotech.com\/tag\/windows-11\">Windows 11<\/a> and Windows 10, Microsoft is gradually validating and updating Secure Boot certificates through standard system updates. In most cases, you only need to keep up with the <a href=\"https:\/\/pureinfotech.com\/install-updates-manually-windows-11\/\">monthly security updates<\/a> to ensure your device is ready before the June 2026 deadline.<\/p>\n<p>However, if you want to verify or apply the newer 2023 Secure Boot certificates yourself, you can complete the process manually. This guide walks you through the steps.<\/p>\n<p><a href=\"https:\/\/pureinfotech.com\/enable-secure-boot-windows-11\/\">Secure Boot<\/a> is a firmware-level security feature built into the Unified Extensible Firmware Interface (UEFI). It ensures that a device starts only with software digitally signed and trusted by approved certificate authorities. By validating bootloaders and firmware components before the operating system loads, Secure Boot helps prevent rootkits and other low-level malware from compromising the startup process.<\/p>\n<p>To enforce this protection, Secure Boot relies on cryptographic keys known as certificate authorities (CAs). These keys establish a chain of trust between the firmware and the operating system, blocking unsigned or tampered code during early boot.<\/p>\n<section class=\"custom-related-posts-wrapper\"><span class=\"custom-related-posts-heading\">Related<\/span><div class=\"custom-related-posts-container\"><a href=\"https:\/\/pureinfotech.com\/check-secure-boot-certificates-expiration-windows-11\/\" class=\"custom-related-post-item\" data-umami-event=\"related_inpost_clicked\" data-umami-event-name=\"How to check if your PC has the updated Secure Boot certificates on Windows 11, 10\"><div class=\"custom-related-post-thumbnail\"><img src=\"https:\/\/i0.wp.com\/pureinfotech.com\/wp-content\/uploads\/2026\/02\/windows-11-check-secure-boot-certs-hero.webp?fit=300%2C188&#038;quality=78&#038;strip=all&#038;ssl=1\" alt=\"How to check if your PC has the updated Secure Boot certificates on Windows 11, 10\" decoding=\"async\" loading=\"lazy\" \/><\/div><span class=\"custom-related-post-title\">How to check if your PC has the updated Secure Boot certificates on Windows 11, 10<\/span><\/a><\/div><\/section>\n<p>Similar to all digital certificates, Secure Boot certificate authorities have expiration dates. The original 2011 certificates expire in June 2026. Systems must have the updated 2023 certificates installed before that date to avoid trust validation errors, boot issues, or potential interruptions in receiving future updates.<\/p>\n<p>Computers manufactured in 2024 or later typically ship with the 2023 certificates already in place. For older hardware, Microsoft is delivering the updated certificates through Windows Update as part of ongoing security maintenance, but you can also install and replace the new certificates manually.<\/p>\n<p>In this <a href=\"https:\/\/pureinfotech.com\/tag\/how-to\">guide<\/a>, I&#8217;ll outline the easy steps to check and manually update the Secure Boot certificates on your Windows 11 device.<\/p>\n<div id=\"tip-box\"><span><strong>Important:<\/strong> Although this is a non-destructive process, it&#8217;s still recommended that you make a <a href=\"https:\/\/pureinfotech.com\/create-backup-windows-10-macrium-reflect\/\">full backup of your computer<\/a> before proceeding. <strong>You&#8217;ve been warned.<\/strong><\/span><\/div>\n<h2>Install the 2023 Secure Boot certificates on Windows 11<\/h2>\n<p>If BitLocker is active, you must <a href=\"https:\/\/pureinfotech.com\/disable-suspend-bitlocker-windows-11\/\">disable the encryption<\/a> temporarily in PowerShell (<code>Suspend-BitLocker -MountPoint \"C:\" -RebootCount 2<\/code>) before the firmware can successfully write the new keys to the device. Also, before proceeding, make sure your <a href=\"https:\/\/pureinfotech.com\/install-updates-manually-windows-11\/\">computer is fully updated<\/a> to the February 2026 Security Update (KB5077181) or later.<\/p>\n<p>To update the Secure Boot certificates before expiring in 2026, follow these steps:<\/p>\n<ol>\n<li>\n<p>Open <strong>Start<\/strong>.<\/p>\n<\/li>\n<li>\n<p>Search for <strong>PowerShell<\/strong> (or <strong>Terminal<\/strong>), right-click the top result, and choose the <strong>Run as administrator<\/strong> option.<\/p>\n<\/li>\n<li>\n<p>Type this command to confirm the device is using UEFI with Secure Boot enabled and <strong>Enter<\/strong>:<\/p>\n<pre>Confirm-SecureBootUEFI<\/pre>\n<div id=\"tip-box\"><span><strong>Quick note:<\/strong> If the output is <strong>&#8220;True,&#8221;<\/strong> you can proceed with the steps below.
