Win PE no longer in 7.5 SP1

I came across the following in the release notes for Deployment Solution 7.5 SP1

The Windows preboot configuration is no longer packaged with Deployment Solution.

To use the WinPE as a preboot environment, you must first download and install the Windows ADK for Windows 8 and then import the Windows ADK to install into Deployment Solution.

This activity consumes around 3 hours.

• Installing ADK takes about 1 hour

• Creating package takes about 30 minutes

• Creation of Bootwiz automation package takes about 1 hour

I see no other documention on how to do this in any of the implementation or user guides. Has anyone come across any more info on this? Will pxe/preboot continue to work normally since it's an upgrade from 7.5 and not a fresh install?
