I have to use windows for a couple of days, and it showed a BSOD when booting after activating WSL2
Update: This bug also prevented me from upgrading to windows 11. The fix below fixes this as well!
One workaround is:
bcdedit /set hypervisorlaunchtype off
but that means that I get to see a
WslRegisterDistribution failed with error: 0x80370102
when starting wsl2 / ubuntu.
The answer is described in https://forums.lenovo.com/t5/ThinkPad-T400-T500-and-newer-T-series-Laptops/BSOD-when-using-Windows-Virtualization-Platform-WSL2-on-T590-T490/m-p/5034580?page=1#5125424
"Disabling "Enhanced Windows Biometric Security" in BIOS Setup -> Security -> Virtualization menu will solve this problem\..."
After having done that, I could turn the hypervisor back on
bcdedit /set hypervisorlaunchtype auto start
No more bluescreen, and ubuntu on windows 10. Thanks 'someotherguy'!
