Last week, Microsoft rolled out its latest Patch Tuesday updates for Windows 11, specifically KB5094126 and KB5093998. In conjunction with these updates, the tech giant also introduced a series of dynamic updates identified as KB5094149, KB5095971, and KB5094156.
Emerging Issues Post-Update
While Microsoft has not officially reported any significant problems associated with these releases, a number of users have taken to online forums to express their frustrations. The issues reported vary widely, encompassing access difficulties with OneDrive and Dropbox, BitLocker recovery lockouts, and even instances of blue screens of death (BSOD).
Among the most prevalent issues appears to be affecting HP systems, where users have encountered the 0xc0430001 BSOD error following the installation of KB5094126. This situation raises questions about a potential link to a previously reported bug affecting HP devices, which involved ongoing Secure Boot certificate updates that resulted in similar complications.
For those grappling with this specific error, it may be essential to verify that the boot.stl file is present on the installation media, such as a USB installer or ISO. If this critical file is absent, users may find their computers unable to boot from the installation media, leading to the aforementioned error code. The boot.stl file plays a vital role in Secure Boot, as it is used to verify the trustworthiness of boot files, necessitating that it aligns with the current Windows version and system architecture.
To ensure the inclusion of the boot.stl file, Microsoft suggests utilizing the Update WinPE script, which automates the image update process and manages the necessary files. Alternatively, users can manually transfer the boot.stl file from the WindowsBootEFI directory on a Windows device to the corresponding folder on their installation media prior to deploying the updated image.
In addition to the blue screen issues, some users have reported that their systems have been freezing after the update, particularly on Lenovo PCs.
Regarding the OneDrive and Dropbox access problems, one user identified a potential conflict with User Account Control (UAC). He noted, “Okay, so I did some digging, and in our environment, KB5094126 breaks OneDrive and Dropbox in Explorer. I went through all our GPOs and found out that the combination of disabling UAC and having my user being a local admin breaks OneDrive in Explorer. … If I enable UAC again, then it works, even with KB5094126 still installed.”
As these issues continue to unfold, many are hopeful that Microsoft will address them promptly.
