Microsoft patches the patch that put Windows 11 in a coma

Microsoft has released a fix for a recent patch that caused some Windows 11 PCs to enter recovery mode due to an error code linked to the May Patch Tuesday update. The issue primarily affected virtual boxes and some physical devices, displaying the message: "Your PC/Device needs to be repaired. The operating system couldn't be loaded because a required file is missing or contains errors. File: ACPI.sys. Error code: 0xc0000098." The fix, identified as KB5062170, does not address an ongoing issue with Noto fonts, where CJK characters appear blurry in Chromium browsers at 100 percent scaling. Users can temporarily adjust the scaling to 125 or 150 percent to mitigate this problem. Microsoft has faced similar challenges with out-of-band fixes in the past, affecting both Windows 10 and Windows Server.

Microsoft ships emergency patch to fix Windows 11 installation issues

Microsoft has addressed a significant issue affecting certain Windows 11 systems after the installation of the KB5058405 security update from May 2025. Users reported encountering 0xc0000098 recovery errors linked to ACPI.sys, indicating that the operating system could not be loaded. This problem primarily affects Windows 11 versions 22H2 and 23H2 in enterprise settings, particularly among Azure Virtual Machines, Azure Virtual Desktop, and on-premises virtual machines hosted on platforms like Citrix or Hyper-V. Microsoft has released the KB5062170 non-security out-of-band update to resolve the installation and boot problems, which can be manually installed from the Microsoft Update Catalog. For Azure customers facing difficulties after implementing the May 2025 update, Microsoft recommends using Azure Virtual Machine repair commands as a temporary workaround. Users of Windows Home or Pro editions in home environments are unlikely to encounter these issues.

Microsoft Warns Windows Users—Emergency Update Within Days

Microsoft is addressing issues with the May 13, 2025 Windows security update (KB5058405) that is failing to install on some Windows 11, version 22H2 and 23H2 devices. An out-of-band update is planned to be released shortly. A recovery error message indicating that “your PC/Device needs to be repaired” may appear, with the root cause identified as an ACPI.sys driver problem, potentially showing the error code: 0xc0000098. Most reports of this update failure have come from virtual environments, affecting enterprise users more than home users. Earlier in May, a similar emergency update was issued for Windows 10 users experiencing a BitLocker Recovery screen during the installation of a security update.

Microsoft May Patch Tuesday fails on some Windows 11 VMs

Microsoft's recent Patch Tuesday update for Windows 11 has faced significant issues, particularly affecting users on versions 22H2 and 23H2. The installation of the May 13 update is failing on some machines, especially in virtual environments, leading to recovery mode entries and boot errors. Users are advised to avoid the update temporarily. The error message indicates a problem with the ACPI.sys file, which is crucial for managing hardware resources. Windows 11 Home and Pro users are likely unaffected, as virtual machines are typically used in enterprise settings. Microsoft has not provided the number of impacted users or a workaround beyond uninstalling the patches, but engineers are working on a resolution. This incident follows previous patching challenges faced by Microsoft this year, including an emergency update for Windows 10 and issues with Remote Desktop sessions in earlier updates.

Microsoft Tells Nearly All Windows Users—You Must Reboot Your PC

This month's KB5058497 update for Windows 11 24H2 introduces the first 'hotpatch' update, allowing installation without a reboot, but it is only available for Windows 11 24H2 Enterprise users. There is no timeline for extending this feature to Pro and Home users. To use hotpatch updates, users must have a Microsoft subscription that includes Windows 11 Enterprise E3, E5, or F3, Windows 11 Education A3 or A5, or a Windows 365 Enterprise subscription, along with devices running Windows 11 Enterprise version 24H2 (Build 26100.2033 or later), an x64 CPU, Microsoft Intune for deployment management, and Virtualization-based Security (VBS) enabled. Users of Windows 11 24H2 or older versions must reboot their systems to apply new security updates, except for specific patches for Windows Defender, while every third update will still require a reboot. KB5058497 is scheduled to be released between May and June 2025 during the 'no restart' period, and it has been reported to install seamlessly without prompting for a reboot. Users of Windows 11 Home and Pro still face the traditional monthly reboot requirement for updates.

Windows 10’s latest update packs a nasty bug, and while your system might be safe, it’s vital you check now

Windows 10 users are experiencing issues with the May update, which has a bug affecting business laptops with Intel vPro processors. This bug can cause update installation failures and repeated automatic repair attempts. Microsoft has released an emergency fix, KB5061768, which users should apply before installing the May update. The problem stems from the termination of the lsass.exe service, leading to automatic repair failures and potential lockouts for users with Device Encryption or BitLocker. To recover, users may need to disable Intel Trusted Execution Technology (TXT) and Intel VT for Direct I/O in BIOS settings, which typically requires the BitLocker recovery key. A workaround allows users to disable Intel TXT without changing Intel VT settings. Users can access BIOS by pressing keys like F2, F10, or F12 during startup, navigate to the Intel TXT setting, disable it, and then restart their PC to install the emergency patch. It is recommended to install the emergency fix before downloading the May update. Similar bugs have occurred in previous updates for Windows 10 and 11. Windows 11 users should note that a clean install of version 24H2 automatically applies Device Encryption, which requires careful management of Microsoft account credentials for recovery keys.

Microsoft releases emergency hotfix for Windows 10’s May update issues

Microsoft released an out-of-band update, KB5061768, for Windows 10 users to address urgent security vulnerabilities. This update is available through the Microsoft Update Catalog for Windows 10 versions 1903 and later, including Windows 10 LTSB, and supports both x86 and x64 architectures. The download size ranges from 415 MB to 711 MB. The update is crucial for users experiencing BitLocker issues and blue screen crashes after the May Windows 10 patch, particularly on devices with Intel Trusted Execution Technology enabled on 10th-generation Intel vPro processors or newer. Users unable to install the update due to boot issues should disable Intel VT for Direct I/O and Intel Trusted Execution Technology in the BIOS/UEFI settings to allow normal startup and apply the update.
