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 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.
