Recently global users installing Windows 10 August update have started facing Windows BSOD (Blue Screen of Death) screen error randomly on their system. Some users have experienced a complete crash of the system and slow performance during the boot.
Lenovo is one of the first vendors to acknowledge the BSOD error. A bug in Window 10 KB4566782 and Lenovo’s BIOS is causing ThinkPad laptops to get stuck in BSOD. Lenovo has officially provided a workaround after investigating the cause of this error. According to Lenovo, this error usually occurs when Vantage app is trying to use the Intel Management Engine to interface with the firmware, but the process is prevented by this BIOS setting and Windows 10’s August update.

Lenovo has provided a step by step solution to deal with this situation. Please note that the solution below is applicable only for Lenovo ThinkPad models.
