Microsoft confirms Windows 11 may restart multiple times after updates and your PC isn’t broken, as it’s due to Secure Boot 2023

Upon installing the April 2026 Patch Tuesday update, some users experienced two or three reboots, which Microsoft confirmed is intentional due to the installation of Secure Boot 2023 certificates. This behavior is expected for a limited number of devices and is part of the Secure Boot update process. The Secure Boot certificates are replacing older ones issued in 2011, set to expire in June 2026. Users can check their Secure Boot status in the Windows Security app, which indicates the status with green, yellow, or red badges. A green badge means the system is up to date, while yellow and red badges indicate issues with certificate updates. Microsoft is managing Secure Boot certificates on modern PCs, but older machines without OEM support may struggle to receive updates due to firmware limitations.

April 2026 Windows Update Breaks Third-Party Backup Software by Blocking Vulnerable Driver

Microsoft will include the psmounterex.sys driver in its Vulnerable Driver Blocklist in the April 2026 security update, affecting third-party backup applications that use this driver for image mounting and Volume Shadow Copy Service (VSS) snapshots. This decision addresses CVE-2023-43896, a critical buffer overflow vulnerability. Affected software includes Macrium Reflect, Acronis Cyber Protect Cloud, UrBackup Server, and NinjaOne Backup on Windows 11, Windows 10, and Windows Server platforms. Users may face issues during image-mount operations, receiving error messages related to VSS timeouts and Code Integrity errors in the Event Viewer. To check if a system is affected, users can look for Event ID 3077 in the Code Integrity Operational log. Microsoft recommends upgrading to newer versions of backup applications that do not use blocked drivers and advises against uninstalling or delaying the April update. Additionally, the update may cause certain Windows Server 2025 devices to boot into BitLocker recovery mode and has led to out-of-band updates for Windows Server update failures and restart loops on domain controllers.

Windows 11 restarts several times after a recent update? Don’t panic

After the installation of the optional April 2026 update, users may experience multiple restarts of their PCs, which is normal due to the Secure Boot certificate refresh process. This behavior may also occur with future updates as Microsoft implements Secure Boot certificate refreshes. Windows updates typically require a single reboot, but significant feature updates or firmware and driver updates may necessitate two or three reboots. Many Windows devices manufactured before 2024 have outdated Secure Boot certificates that need updating, as these certificates will expire in June 2026. Microsoft began rolling out updated Secure Boot certificates in March, but this rollout is staggered. Users can check their PC's Secure Boot certificate status in Windows Security under "Device security." The status is indicated by colored icons: green (up to date), yellow (update pending), and red (action required). Older devices may face issues with the certificate refresh if they lack up-to-date firmware or compatible BIOS updates. If Windows reports an error, the device manufacturer is typically responsible for resolving it. Users should verify that Secure Boot certificates were installed correctly after updates to ensure continued secure booting beyond June.

Microsoft is finally ditching the junk MSN feed in Windows widgets

Microsoft will eliminate the MSN news feed from the widgets panel in Windows 11, shifting to a "quiet by default" experience. This change includes disabling the automatic opening of the widgets panel when hovering over its taskbar icon and turning off distracting taskbar badges by default. Users will now see a more personalized set of information in the widgets panel instead of notifications related to stocks, weather, or news. These updates aim to create a less distracting interface and improve the overall user experience in Windows 11, with further enhancements expected throughout 2026.

Xbox Mode provides a full-screen user interface optimized for controller use, displaying only one application at a time to minimize distractions. Players can switch between Xbox Mode and the traditional Windows 11 desktop and Xbox Game Pass subscribers can navigate their game libraries easily. Xbox Mode was initially available for testing in late 2025 and officially started its public rollout on April 30, with deployment occurring in waves across various regions.

Defender yanks root certs as Windows updates blocks backups

Microsoft's Defender anti-malware tool update version 1.449.425.0 removed two DigiCert root digital certificates, leading to false positives that flagged them as severe malware (Trojan:Win32/Cerdigent.A!dha). This incident was later identified as a false positive, and updating to version 1.449.430.0 or later reinstates the certificates. The issue may be linked to a DigiCert employee encountering disguised malware. Additionally, Windows updates from April 14 caused third-party backup applications to malfunction due to the addition of vulnerable psmounterex.sys kernel driver versions to a blocklist. Users experienced difficulties with mounting backup image files, and Microsoft referenced a vulnerability rated 9.3 out of 10 in the driver. Other affected software includes Acronis Cyber Protect Cloud and UrBackup server. Microsoft has not explained the delay in adding the vulnerable driver to the blocklist, and other recent update-related issues have also been reported.

Microsoft’s new Windows 11 Run dialog is faster than the Windows 95-era version it’s replacing

Microsoft is developing a modernized version of the Run dialog for Windows 11, featuring a streamlined design created using C# and WinUI 3. The new Run dialog has a median "time-to-show" of 94 milliseconds, which is an improvement over the old dialog's 103 milliseconds. This new version is designed to be more functional and user-friendly, allowing users to quickly access their home directory and supporting dark mode. The modern Run dialog is currently being rolled out as an opt-in feature for Insiders in the Experimental Channel.
