TL;DR version

  1. Generate a new WinPE mage by running the BranchCache for OSD generator tool

    1. Decide if you want to use StifleR or not, if so, add the /Add-StifleR parameter on the command line

  2. Modify the Task Sequence and add two steps:

    1. Run "BCEnabler.exe Enable" in your sequence to enable BranchCache and BITS services

    2. Run "BCEnabler.exe Move" in your sequence to move the data cache to the new full OS

    3. Set the SMSTSDownloadProgram variable to ‘BITSACP.exe’ to enable BITS downloads in the Task Sequence

  3. Done!
