As Microsoft rolled out the Technical Preview for IT Professionals, we have found many features disabled by Microsoft in the current build. Another thing I just found are the traces of Biometrics and Quiet Hours. Although, Finger Print Biometric sensor was already supported in Windows 7 and Windows 8, but seeing this may suggest that we can have eye scanning or face recognition from Microsoft as well. Moving towards Quiet Hours, I think it is a bit natural as we already say Cortana in the system files. As Quiet Hours is a part of Cortana, so we will have that on our PC soon. For now we don't know the real motive of Microsoft and what they are going to do in near future. I will update the article if we found some details. Till then see the images below for the same and stay tuned as we dig more in the new Operating System.
