Windows 10 IoT Enterprise for Dell Wyse Thin Clients Administrator’s Guide

Blue screen error or BSOD issues

A blue screen error or BSOD with error code CRITICAL PROCESS DIEDCRITICAL PROCESS DIED is observed on Wyse 5070 thin client with Apacer Solid-State Drives running Windows 10 IoT Enterprise version 10.03.06.10.18.00. To resolve this issue, you must disable the link power management mode for storage devices that are connected to the thin client using an AHCI interface.

NOTE: This issue is resolved in Windows 10 IoT Enterprise image builds later than version 10.03.06.10.18.00, and hence you are not required to apply the registry entry manually.

To disable the link power management mode using a registry file, do the following:

1. Log in as an administrator.
2. Disable Unified Write Filter.

   The system restarts.

3. Log in as an administrator again.
4. Open Notepad and type the following syntax:
