i updated the guide i test it and its wasnt good the system wont load up cos the backup and Manifests dirs but now its update-able but need to save the backup files of Iexplorer too to make it perfect i checked how much space its save 32bit 800mb [ my windows dir is 1.6giga] 64bit 1600mb [ didnt test it cos dont have VT so i guess the install size would be 3giga from 4.4giga ofc my settings] im not sure if its recommand to do on wim file cos there a files that wont delete [system use them] the best is do updating and then remove them [so u wont need to guess what the backup files of Iexplorer ] check picture to more info
