Another week brings yet another emergency update for Windows users, as Microsoft continues to navigate the complexities of its operating systems. Just days after alerting users to issues with May’s security update, the tech giant has confirmed that it is actively addressing the problem and plans to roll out an emergency update shortly. The company has reassured Windows users that it “plans to release an out-of-band update in the coming days.”
Details of the Update
This situation predominantly affects Windows 11 users, although echoes of a similar emergency update for Windows 10 users earlier this month can be felt. Microsoft has promptly acknowledged the situation, stating that it is “investigating reports of the May 13, 2025 Windows security update (KB5058405) failing to install on some Windows 11, version 22H2 and 23H2 devices.” As anticipated, the next logical step is the introduction of an out-of-band update.
For those impacted, a recovery error message will appear, indicating that “your PC/Device needs to be repaired,” and that “the operating system couldn’t be loaded because a required file is missing or contains errors.”
Microsoft has identified the root of the issue as an ACPI.sys driver problem, which may present the error code: 0xc0000098. The ACPI.sys file, which stands for Advanced Configuration and Power Interface, is a vital Windows system driver that facilitates the management of hardware resources and power states. The company has also noted that there are reports of this same error manifesting under different file names.
Impact on Users
While some physical devices have been affected, the majority of reports regarding this update failure have emerged from virtual environments. These include Azure Virtual Machines, Azure Virtual Desktop, and on-premises virtual machines hosted on platforms such as Citrix or Hyper-V. Consequently, it appears that enterprise users are more likely to experience disruptions than home users.
This situation contrasts with the earlier emergency update in May, which addressed issues faced by Windows 10 users who encountered a BitLocker Recovery screen when attempting to install the security update. Microsoft had warned that “Windows 10 might repeatedly display the BitLocker recovery screen at startup,” confirming the necessity of another out-of-band update.
