By using the AOMEI Windows PE Builder (free), we can quickly build a useful 32-bit or 64-bit WinPE ISO in just a few minutes and with just a few clicks.
Note: I recommend building first the 32-bit ISO because the 64-bit version will not contain WoW64 and so will not be able to run 32-bit applications such as PortableApps (but you can add Desktop shortcuts to 32-bit and 64-bit apps in the \AIO folder using PEStartUp).
Also, because the WinPE has no added extra Windows components, some added portable applications (such as Chrome, Opera and Mozilla, etc.) may not run correctly (e.g. 'couldn't load XPCOM' error). The provided QtWeb browser Desktop link does work however.
