Handling UMDF Verifier Failures

The UMDF Verifier causes failures in UMDF driver code to bug check the host process. However, a UMDF bug check does not cause a blue text screen to appear with information about the error. Instead, a UMDF bug check:

  • Creates a memory dump file and saves the file to the computer's log file directory (for example, %windir%\System32\LogFiles\WUDF\Xxx.dmp).

  • Creates an error report for Microsoft (opt-in).

  • Breaks into the debugger if one is attached to the computer. The debugger prints an out error message. You can continue but the computer might stop responding again.

  • Terminates the host process and disables the device.
