Hey there. My hp envy has a recovery partition,on that Partition there is a 15 GB Install.wim file,when I explored the file using 7-zip,I found 5 folders named :1,2,3,4,[files] respectively . Note that the partiton has bootmgr and bootmgr.efi files ,and boot and efi folders. My guess the first 4 four folders contain different versions of windows 8, and one folder  contains the drivers. how can I know which version is in each folder? And how can I make an Iso from the desired one? Thanks in advance. Edit: Added Screenshot of WIM file details ,can someone explain which one to use and how?
