A segment of Windows 11 users has been unable to receive updates since February due to issues stemming from the January Preview Update, which caused download timeouts. This has resulted in missed security patches and critical updates related to Secure Boot certificates. Users may experience crashes during the update process, indicated by the error code 0x80010002. To check if affected, users can view their update history in Settings; if no updates have been installed since January and updates have not been paused, they are likely impacted. Microsoft is working on a fix linked to download timeout changes and firewall settings. A Known-Issue Rollback (KIR) can be executed to revert to a previous state before the problematic update, restoring normal functionality. This rollback is available for specific Windows 11 versions and Windows Server 2025.

Users have observed a new folder named “SecureBoot” in the Windows system folder following the installation of Windows 11's May update (KB5089549). This update may cause installation issues for some devices and introduces a directory that contains example scripts for IT professionals to manage Secure Boot certificate updates. Windows Secure Boot certificates are set to expire next month, and outdated certificates will lead to loss of support starting in June, potentially compromising Secure Boot functionality. Microsoft is distributing new certificates through Windows Update. The SecureBoot folder does not require individual users to take action, and deleting it is discouraged as it may cause complications with future Windows updates.

Microsoft has issued a service alert indicating that customers in restricted network environments may encounter Windows Update failures, specifically error code 0x80010002, after installing the January 2026 optional non-security preview updates. Affected devices might download the February monthly Windows security update but could struggle with updates released in March and beyond due to changes in download timeout requirements. Microsoft is working on a resolution, and IT administrators can use Known Issue Rollback (KIR) as a workaround by configuring the appropriate Group Policy for their Windows version. A device restart is required to apply these settings. Historical issues include a bug fixed in April 2025 affecting WSUS installations and another issue resolved in August 2025 related to the Windows 11 24H2 cumulative update. Additionally, a KIR fix was provided for a known issue causing the May 2026 Windows 11 security update to fail with error code 0x800f0922.

System Restore is a recovery tool in Windows that allows users to revert their systems to a previous state, originating with Windows ME. It generates restore points that can be created manually or automatically, with a maximum retention of 60 days starting from the Windows 11 24H2 update in 2025. System Restore captures essential system files and settings but does not recover personal files. The new Point-in-Time Restore feature, introduced in 2025 and appearing in the Windows 11 Insider Experimental preview in April 2026, captures a broader range of data, including user files and applications, and operates on a scheduled basis with snapshots retained for up to 72 hours. It is optional for standard users, enabled by default for PCs with 200GB or more storage, and has storage limits set to 2% of total drive capacity. In enterprise settings, it is always enabled for Windows 365 Enterprise, maintaining restore points for up to one month and utilizing cloud storage. Point-in-Time Restore aims to improve the recovery experience and address limitations of the classic System Restore.

Beginning in May 2026, Microsoft will introduce Hotpatching as a default feature for compatible systems, allowing security updates to be applied without requiring a restart. Hotpatching updates code directly in the memory of running processes, enabling selective updates without interrupting the entire system. It does not replace monthly security updates but alters their activation process on eligible systems, categorized as security updates within the monthly B releases. Eligible systems must be running Windows 11 version 24H2 or newer and possess suitable licenses such as Enterprise, Education, Microsoft 365, or Windows 365. Management of these updates will be facilitated through Windows Autopatch or Microsoft Intune. Microsoft will continue to utilize baseline updates that require a restart, which will alternate with Hotpatch months. Hotpatching aims to reduce the frequency of restarts tied to security updates, particularly benefiting environments where uptime is critical. However, planned restarts will still be necessary, and robust telemetry and maintenance practices will be needed to ensure smooth operation.

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 has updated its Windows 11 operating system to enhance the management of preinstalled applications. The new RemoveDefaultMicrosoftStorePackages policy allows IT administrators to remove any preinstalled MSIX/APPX applications by referencing their Package Family Name (PFN) through Group Policy Object (GPO) or custom OMA-URI for mobile device management (MDM). This feature requires devices to have at least the April 2026 Windows non-security update. It is available for Windows 11 version 24H2 Enterprise and Education editions, whereas it was initially exclusive to version 25H2 or later. A comprehensive list of supported applications and instructions for applying the policy are provided in Microsoft's documentation. Additionally, a new policy setting enables the uninstallation of the AI-powered Copilot digital assistant from enterprise devices after the April 2026 Patch Tuesday updates. The dynamic list option for this policy will be rolled out in the coming months.
