Microsoft have released an update to Window 10 21H1 for Windows Insiders on the beta and release preview channels. KB5001391 takes the build to 19043.964 and has just the one fix:

  • We fixed an issue causing a 0xC2 (BAD_POOL_CALLER) bugcheck when using IOCTL_SCSI_PASS_THROUGH_DIRECT.

The 21H1 update which we now know will be called the Windows 10 May 2021 Update and released next month.
