The SlicedEncryptionInPlace setting works with other settings in the microsoft-windows-securestartup-filterdriver- component to optimize BitLocker settings for PCs with hardware architectures such as System on a Chip (SoC). Do not use these settings for standard 32-bit or 64-bit hardware architectures.
These settings are intended for OEM manufacturing only. For specific guidance on using these settings, contact Microsoft.
Note These settings only apply to Windows 8.
Values
