Surface Book 4 and Surface Pro 4 tablets have recently begun to complain about battery depletion, which has greatly reduced the working time of these devices. Although the official reason is not known, but there is a high probability that it is responsible for Windows Hello.

Microsoft has introduced it to make it easier to log on to the computer and replace the previously used passwords. The software supports biometric technologies, that is face recognition, iris and fingerprints, and protects the equipment by preventing unauthorized access to the data collected.
