Windows 11 Latest Update Causing BSODs, Boot Failures, and OneDrive Issues for Some Users

Microsoft Windows 11 latest update, KB5094126, was released to improve system security and performance, but many users are reporting serious issues after installing it. While the update addresses more than 200 security vulnerabilities, it appears to be causing boot failures, Blue Screen of Death (BSOD) errors, and File Explorer problems on certain PCs.

Windows 11 Latest Update Causing BSODs, Boot Failures, and OneDrive Issues for Some Users

One of the most serious issues linked to the June 2026 update is boot failure. Several users have reported that their systems enter BitLocker recovery loops after installation, preventing Windows from starting normally.

Others have encountered Black Screen of Death errors, Secure Boot signature problems, and the error code 0xc0430001 during startup. In some cases, affected PCs become completely unusable until recovery procedures are performed.

Reports suggest that the issue is primarily affecting enterprise-focused devices, including several HP and Dell models.

Reported Affected Devices

The following systems have been frequently mentioned in user reports:

• HP EliteBook 840 G10
• HP ProBook 460 G11
• HP Engage One Pro G2 AiO POS
• HP ZBook series
• Certain Dell Precision workstations

Although the issue does not appear to affect every device running these models, the number of reports indicates a possible compatibility problem between the update and specific hardware configurations.

Possible Cause Behind the Boot Issues

Early investigations point to a combination of Secure Boot certificate updates and limited EFI partition space as the likely cause.

Many older Windows installations use a 100MB EFI system partition. During the update process, Windows may attempt to update boot-related files and Secure Boot certificates. If there is insufficient space available in the EFI partition, the update may fail, resulting in boot errors or recovery loops.

The problem may be more common on some HP systems, where firmware recovery files can consume additional EFI partition storage over time.

OneDrive and Cloud Storage Integration Problems

The update is also causing issues within File Explorer.

Several users report that OneDrive shortcuts no longer open correctly from the File Explorer navigation pane or system tray after installing KB5094126. Similar behavior has also been observed with other cloud storage services, including Dropbox and iCloud Drive.

While files remain accessible through alternative methods, the broken integration can disrupt workflows for users who rely heavily on cloud storage.

Custom Folder Icons May Stop Working

Another change introduced with the update affects custom folder icons and localized folder names.

Microsoft has confirmed that new security protections for desktop.ini files can prevent Windows from loading custom folder settings from sources that are not considered trusted.

As a result, some folders may lose their custom icons or display default names instead of localized labels. Although this behavior is intentional from a security perspective, it may surprise users who have customized their folders.

Should You Install KB5094126?

Despite the growing list of issues, KB5094126 remains an important security update. Microsoft says it fixes more than 200 vulnerabilities, making it a significant release for protecting Windows systems against potential threats.

However, users with affected hardware, especially enterprise devices with older EFI partition configurations, may want to proceed with caution. Creating a full system backup before installation and verifying available EFI partition space could help reduce the risk of update-related problems.

Final Thoughts

The Windows 11 KB5094126 update highlights the challenge of balancing security improvements with system compatibility. While the patch delivers important security fixes, reports of BSODs, BitLocker recovery loops, Secure Boot failures, and broken cloud storage integration have raised concerns among users.

Microsoft has yet to provide a widespread fix for all reported issues, so affected users should monitor official support channels for updates and workarounds. Until then, organizations and power users may want to test the update carefully before deploying it across multiple systems.
