You cannot cancel and immediately restart facial recognition setup in Windows 10, version 1809, Windows Hello

On the Set up Windows Hello page of the Windows Setup process, you select Use face recognition and then select Set up. On the next page, you cancel the setup process by selecting the "x" character in the upper right corner of the photo preview window. Windows returns you to the Set up Windows Hello page, and you select Use face recognition > Set up again.

Instead of the photo preview window, you see a blank (all black or all white) page.

This is a known issue in Windows 10, version 1809.

To escape from the blank screen and restart the Windows Hello face recognition setup process, follow these steps:

1. Do one of the following:
   • Select the "x" character in the upper right corner of the page
   • Press Alt + F4 (if the "x" is not visible)
2. Wait for the camera indicator LEDs to turn off.

   Important

   On most PCs, indicator LEDs flash while the camera and the infrared illumination system is active. After you cancel the Setup process, these LEDs continue to flash for a few seconds. This flashing indicates that the system is not ready to restart.

3. After the LEDs stop flashing, you can select Use face recognition > Set up again.
