I want to make a PE with XP (preferably), or 7. Beside DiskCryptor, and Macrium Reflect Free, I don't really need anything else.
But I don't know what to use - this website has WinBuilder 2013.09.01 as a featured download. The tutorials I've found are for some undisclosed versions (but not that ^ one). Even your own tutorial from here:
http://reboot.pro/topic/4111-newcomers-tutorial-livexp-win7pe-portable-apps/
just adds to my confusion:
The projects discussed in this tutorial are customized and frozen versions of their progenitors, LiveXP and Win7PE_SE. They are more or less updated to reflect their counterparts but have different setups and contain additional scripts and features not offered in the official versions found elsewhere in the forum.
My only other PE experience was with BartPE, so I'm a "little" overwhelmed 
I got other questions too, but let's take it one step at a time
