Description

This should help root cause the occasional hangs we've seen when stopping the prjflt service.

If the verifier detects issues it will bugcheck the system and the ProjFS team can be provided with the dump.

To enable driver verifier

  1. verifier.exe /standard /driver prjflt.sys
  2. reboot

If this does not detect the issue triggering the hang, we can try turning on the verifier for fltmgr.sys as well.

To confirm the verifier is enabled

verifier.exe /query
verifier.exe /querysettings

To disable the verifier

  1. verifier.exe /reset
  2. reboot

Research direction

Start with the Windows functional test machines and the verifier.exe commands listed in the issue. Enable standard verification for prjflt.sys, reboot, and use verifier.exe /query and /querysettings to confirm it. Done means the verifier is active for the test run and any resulting bugcheck dump can be provided to the ProjFS team; use /reset and reboot to disable it.
