    Fault : STOP 0x0000001E -- KMODE_EXCEPTION_NOT_HANDLED
    Fix   : Find the driver when nothing is named
    Source: https://jbtecwiz.com/support/win-0x1e

    Run as     : WinDbg
    Expect     : 1-2 days
    Risk       : medium
    Reversible : yes

    WHEN THIS IS THE RIGHT FIX
    The screen blames ntoskrnl.exe, which almost never means the kernel is
    at fault -- it means the kernel was executing on someone else's behalf.

    HOW TO UNDO IT
    verifier /reset from Safe Mode or WinRE if Verifier makes the machine
    unbootable.

    This script walks the fix one step at a time and asks before each
    one. Steps with no command are things you do yourself -- it prints
    those and waits. Run with -DryRun to print without executing.
