Windows 10 makes use of Face Detection and Recognition technology in Windows Hello login and the Photos App. If you do not want to use this feature, you can Disable Face Detection, both in Windows Hello and Photos App.
Disable Face Detection in Windows 10
The purpose of incorporating Face Recognition technology and Biometric sensing in Windows 10 is to allow users to login to the computer using Face ID, Fingerprint and Iris scanning.
In case of Photos App, Face Detection technology is used to identify people appearing in Photos stored on your computer and put them together in groups for your convenience.
According to Microsoft, the process of Face Detection in Photos App happens right on your device and all the Face Detection Data can be erased by disabling the “People” setting in Photos App.

On the Settings screen, scroll down to “Viewing and Editing” section and move the People setting to Off position.

If you happen to change your mind, you can Enable Face Detection and Recognition back on your computer by repeating the steps above and moving the People toggle to ON position.
