Confirm Device Is in a Trusted/Secured State

Vanguard checks for a few settings to make sure your computer is in a trusted/secured state—namely, that Test Signing Mode is disabled and that you're using Driver Signing Enforcement.

  1. Press the Windows key.
  2. Type cmd.
  3. Select Run as administrator in the right column.
  4. Enter the following two commands exactly as written below, while pressing Enter after each command:
    • bcdedit /set TESTSIGNING off
    • bcdedit /set nointegritychecks OFF
  5. Restart your computer.

Disable Debug Memory Dump

Try changing these settings through the following steps:

  1. Press the Windows key.
  2. Type sysdm.cpl, then press Enter.
  3. Go to the Advanced tab > Startup and Recovery > Settings.
  4. Change the Write debugging information dropdown to (none).

  3. Go to Programs Programs and features.
