While installing the May Windows security update (KB5058405) on the Windows versions listed below, some devices might encounter the following recovery error:

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

This issue has been observed on a small number of physical devices, but primarily on devices running in virtual environments, including:

Azure Virtual Machines
Azure Virtual Desktop
On-premises virtual machines hosted on Citrix or Hyper-V

Home users of Windows Home or Pro editions are unlikely to face this issue, as virtual machines are mostly used in IT environments.

The ACPI.sys file (Advanced Configuration and Power Interface) is a critical Windows system driver that enables Windows to manage hardware resources and power states. Note: There are also reports of this same error occurring with a different file name.

Resolution:

This issue is resolved in the out-of-band (OOB) update KB5062170, which is only available via the Microsoft Update Catalog. If you experienced this issue, or if you have not yet deployed the May 2025 Windows security update on the Windows versions listed below and your IT environment includes devices running in a virtual desktop infrastructure, we recommend you apply the out-of-band update instead.

Note: This out-of-band update contains all of the improvements and fixes included in the May 2025 Windows non-security preview update (KB5058502), in addition to this issue’s resolution. Since this is a cumulative update, you do not need to apply any previous update before installing KB5062170, as it supersedes all previous updates for affected versions. This update does not contain any additional security updates from those available in the May 2025 Windows security update. Installation of this OOB will require a device restart.

If you experienced this issue and are unable to start Windows, please try the following steps to recover your device. After you've recovered your device, install the out-of-band update (KB5062170) via the Microsoft Update Catalog.

On Recovery-enabled devices:

Access the Windows Recovery Environment.
Restart Windows.

On non-Recovery enabled devices:

Mount the virtual hard disk (VHD) from a remote device.
Mount the VHD on another virtual machine (VM) or device as a data disk and then return it back to the affected VM.
Restart Windows in normal mode. This will revert Windows to the last successfully installed Windows update.

For Azure customers, we recommend using the self-help repair steps outlined in this article to carry out these steps: Repair a Windows VM using Azure Virtual Machine repair commands.

Affected platforms:

Client: Windows 11, version 23H2; Windows 11, version 22H2
Server: None
