Enable use of BitLocker authentication requiring preboot keyboard input on slates
This policy setting allows users to enable authentication options that require user input from the pre-boot environment even if the platform indicates lack of pre-boot input capability.
The Windows on-screen touch keyboard (such as used by slates) is not available in the pre-boot environment where BitLocker requires additional information such as a PIN or Password.
It is recommended that administrators enable this policy only for devices that are verified to have an alternative means of pre-boot input (such as by attaching a USB keyboard).
Note that if this option is not enabled, options in the 'Require additional authentication at startup' policy may not be available on such devices. These options include:
- Configure TPM startup PIN: Required/Allowed
- Configure TPM startup key and PIN: Required/Allowed
- Configure use of passwords for operating system drives.
