Microsoft Pauses Windows 11 24H2 Update Due to BSOD Problems on Multiple Devices

Key Notes

  • The Windows 11 24H2 update is causing BSOD errors for some users.
  • Issues are particularly noted with certain Western Digital SSDs.
  • Disabling Host Memory Buffer (HMB) can help mitigate BSOD issues.

Troubleshooting BSOD Issues Following the Windows 11 24H2 Update

If you’ve recently upgraded to Windows 11 24H2 and are encountering Blue Screen of Death (BSOD) errors, specifically the “critical process died” message, you’re facing a known challenge affecting users with certain configurations.

The Windows 11 24H2 update has led to widespread reports of BSOD errors predominantly impacting PCs equipped with Western Digital SSDs. This guide aims to elucidate the reasons behind these issues and offer effective solutions for resolution.

Reasons Behind BSOD Issues with WD SSDs

Many users have shared their experiences regarding BSOD occurrences post-Windows 11 24H2 upgrade in community forums. Insights indicate that these BSOD errors are primarily related to malfunctioning storage drivers and RAID controller settings.

Common error messages seen in Event Viewer logs include:

  • stornvme – This references NVMe storage drivers.
  • The driver detected a controller error on \Device\RaidPort1 or 2 – This signifies an issue with the RAID controller, responsible for managing multiple drives.

One concerned user recounted their frustrating experience of acquiring a new CyberPowerPC system, only to return it due to persistent BSOD issues even after reinstalling Windows and reseating the SSD.

Another relevant detail is that the WD SN770 SSD requires a 200 MB Host Memory Buffer (HMB), which functions well with Windows 11 23H2 that allocates only 64 MB. However, the 24H2 update attempts to maximize usage to 200 MB, resulting in the critical process died BSOD error. This problem is also evident with the WD SN580 model.

Fortunately, reports suggest Microsoft is recognizing this dilemma and collaborating with Western Digital to restrict the 24H2 update for the affected hardware.
