A recent Windows 11 update has caused significant boot issues for users. The update in question, KB5058405, was officially released on May 13, 2025, targeting Windows 11 versions 22H2 and 23H2. Within hours of its release, multiple users began reporting severe problems during system startup, highlighting a serious flaw in the update.
What’s the Issue with KB5058405?
The update is leading to boot failures, with systems locking up at startup and showing the following error 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
This error refers to a problem with the ACPI.sys file, which is part of the Advanced Configuration and Power Interface (ACPI) subsystem. This subsystem plays a vital role in Windows by handling power management and hardware discovery. A corruption or improper replacement of this file can disrupt the entire boot sequence, leaving your PC unbootable.
Microsoft’s Response and Affected Systems
Microsoft has acknowledged the issue on the Windows 11 Known Issues page and has provided details about the affected systems:
- Impacted Versions: Windows 11 22H2 and 23H2
- Affected Platforms: Primarily enterprise environments including Azure Virtual Machines, Azure Virtual Desktops, and on-premise VMs hosted via Citrix or Hyper-V
- Risk to Home Users: While Microsoft claims that users of Home and Pro editions are unlikely to be affected, some individual reports suggest otherwise.
So while it’s “unlikely,” it is not impossible for standard users to face this issue. If your system is running Windows 11 22H2 or 23H2, and you are not managed by an IT department, you may automatically receive an upgrade to Windows 11 24H2. However, this does not safeguard you from KB5058405 if it gets installed beforehand.
What You Should Do
If you’re prompted to install KB5058405, consider postponing or pausing the update temporarily—especially if you’re on versions 22H2 or 23H2. Here’s why:
- The update has caused critical errors for many users.
- If you don’t have advanced troubleshooting skills, recovering from this issue may require a fresh install of Windows.
- Avoiding the update can prevent unnecessary downtime and data loss.
Should You Roll Back the Update If Affected?
Yes. If your system becomes unbootable due to this update, you might need to:
- Boot into Windows Recovery Environment (WinRE)
- Use System Restore or Startup Repair
- Roll back the update using Command Prompt
But again, these are advanced steps, and not all users may be comfortable executing them.
The Bigger Problem with Windows Updates
This is not the first time a Windows update has caused system instability. Updates are meant to improve the system, yet sometimes they can introduce new problems—especially when rolled out too quickly.
Many users have gotten into the habit of installing updates immediately upon release. While this ensures security patches are applied, it also increases the risk of running into untested bugs. A better approach is to wait a few days or weeks to see if the update causes problems for other users.
Final Thoughts
The KB5058405 update is a textbook example of why caution is advised when applying newly released Windows updates. While Microsoft has acknowledged the problem and specified its impact on virtual environments, some regular users have also reported issues. Until a more stable version of the update is available, it’s best to delay installation.
