BlueScreens on Thunderbolt Dock
Microsoft had another bug in the Windows 10 May 2020 Update (Version 2004) that caused individual users to run into a BlueScreen (BOSD) when docking or undocking a Thunderbolt dock. The issue has been listed in the status area of Windows 10 Version 2004 for a long time:
Stop error when plugging or unplugging a Thunderbolt dock
Intel and Microsoft have found incompatibility issues when Windows 10, version 2004 (the Windows 10 May 2020 Update) is used with certain settings and a Thunderbolt dock. On affected devices, you might receive a stop error with a blue screen when plugging or unplugging a Thunderbolt dock. Affected Windows 10 devices will have at least one Thunderbolt port, have Kernel DMA Protection enabled and Windows Hypervisor Platform disabled. To verify your Kernel DMA Protection settings, please see How to check if Kernel DMA Protection is enabled. To verify your Windows Hypervisor Platform settings, select Start, type turn windows features on or off and select it. When the Windows Features dialog opens, find the setting for Windows Hypervisor Platform. If it is note checked, then Windows Hypervisor Platform is disabled.
For this reason, Microsoft had set an upgrade lockout for Windows 10 devices with the affected drivers or firmware for Windows 10 version 2004.
Thunderbolt BSOD issue resolved with KB4565503
In the list of fixed 'Issues' in the status area of Windows 10 version 2004, Microsoft states as of 16 July 2020 that the upgrade lock has been removed due to the Thunderbolt issue. The problem is resolved with the KB4565503 cumulative update. This update was released on July 14, 2020. However, I didn't find anything about the Thunderbolt BSOD issue in the information about fixed bugs. If someone is affected by this issue and wants to install the update, take a look at the Known Issues list first – the update might throw errors in Excel when you use the Input Mode Editor (for Chinese and Japanese character input).
