Troublesome Update: Microsoft’s recent non-security preview update, KB5039302, intended for Windows 11 22H2 and 23H2, caused significant issues, leading to its withdrawal1. Users reported boot loops and startup problems, prompting Microsoft to halt further downloads.
Insider Build Woes: This isn’t the first hiccup with Windows Insider builds this month; another bug involved the Windows Cross Device Service consuming excessive CPU resources. Microsoft is investigating the boot loop issue related to virtualization features.
Update Highlights: Despite the problems, the update offered notable improvements, like enhanced File Explorer compression and the reintroduction of the Show Desktop button. It also addressed minor issues with the Snipping Tool and hardware removal processes.
A Cautionary Tale: This incident serves as a stark reminder of the risks associated with immediate updates, especially preview versions. With the upcoming Windows Recall, users are urged to exercise caution and wait for smoother updates in the future.
Boot Loop Problem: A Closer Look
The troublesome update, KB5039302, led to unexpected boot loops for Windows 11 users. When attempting to start their systems, some users found themselves stuck in an endless loop, unable to reach the desktop.
Potential Causes:
- Virtualization Features: Initial investigations suggest that the issue might be related to virtualization features. These features allow multiple operating systems to run simultaneously, but they can sometimes clash with system updates.
- Driver or Compatibility Issues: Another possibility is that specific drivers or software components are incompatible with the update. When the system attempts to load these components during startup, it triggers the boot loop.
- Configuration Conflicts: Windows updates can alter system configurations. If there’s a conflict between the updated settings and existing configurations, it could result in the boot loop.

User Impact:
- Frustration: Users faced frustration as their devices repeatedly restarted without reaching a usable state.
- Work Disruption: Boot loops disrupted work, productivity, and daily tasks for affected users.
Microsoft’s Response:
Microsoft promptly acknowledged the issue and withdrew the update. They are actively investigating the root cause and working on a fix. Users are advised to avoid immediate updates until the issue is resolved.
