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 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 has released an emergency out-of-band update, KB5062170, to address issues from the May 13, 2025 Windows security update (KB5058405), which failed to install on some Windows 11 devices, showing error code 0xc0000098. The new update fixes an issue with the ACPI.sys driver and is available via the Update Catalog. It primarily impacts enterprise environments, particularly virtual setups like Azure Virtual Machines and Azure Virtual Desktop, while home users are less affected. KB5062170 includes all enhancements from the May 2025 non-security preview update and supersedes prior updates, requiring a device restart after installation.

CorePC is an initiative by Microsoft aimed at overhauling the existing monolithic NT architecture of Windows, which has been in use since the 1990s. It seeks to implement a modular framework that allows for customized builds tailored to specific user needs, moving away from the "one size fits all" model. CorePC will introduce state separation of OS components on distinct partitions, enhancing security and streamlining updates. The initiative is expected to reduce system bloat and may lead to the revival of Windows-powered smartphones and tablets with better ARM processor integration. An official launch date for CorePC is not yet available, but it is anticipated to be part of the successor to Windows 11.

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'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.
