Default location of Cmtrace.exe in WinPE 4.0

Pre-provision BitLocker

When you have upgraded to SCCM 2012 SP1 (and WinPE 4.0) the new task sequence step "Pre-provision BitLocker" will be available to you. This means that encryption will start from WinPE, right after the "Format and Partition" steps and "Set OSDDiskPart" and the result is a much faster encryption process. This applicable to Windows 7 and later operating systems.
