Windows 11 April 2025 Update Causing Blue Screen Crashes

April 18, 2025 — Microsoft’s latest Windows 11 update, version 24H2, is causing serious problems for many users. After installing the update, some computers are crashing with the dreaded Blue Screen of Death (BSOD). Others are stuck in endless reboot loops or experiencing system freezes.​

What’s Happening?

The update, released earlier this month, aimed to bring improvements to Windows 11. However, it has introduced several issues:​

Reboot Loops and Freezes: Users report their PCs restarting repeatedly or freezing after the update. In some cases, the system becomes unresponsive, displaying a blue or green screen error. ​

Automatic Repair and BitLocker Recovery: After multiple failed restarts, some devices automatically launch the Windows Automatic Repair tool. Others prompt users for BitLocker recovery keys. ​

Driver Compatibility Issues: The update conflicts with certain Intel Smart Sound Technology (SST) audio drivers, particularly versions 10.29.0.5152 and 10.30.0.5152. This incompatibility leads to BSOD errors on affected systems. ​

SSD-Related Crashes: Some users with Western Digital SN580 and SN770 SSDs experience BSODs due to how Windows 11 24H2 handles Host Memory Buffer (HMB) allocations. The system grants 200MB HMB, which causes crashes with the error “critical process died.” ​

Microsoft’s Response

Microsoft has acknowledged these issues and is taking steps to address them:​

Blocking the Update: The company has placed a compatibility hold on the Windows 11 24H2 update for devices with known incompatible drivers or hardware. This means the update won’t be offered to affected systems until a fix is available. ​

Disable HMB for SSDs: For users with affected Western Digital SSDs, disabling HMB can mitigate BSOD issues. This involves editing the Windows Registry:​

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\stornvme\Parameters\Device

Create a new DWORD (32-bit) value named HMBAllocationPolicy and set its value to 0.​
