First of all, excuse my English. I hope you will understand my question anyway. ;-) I am tweaking a WIN-image of Windows 8.1 for my need, it consist of about hundred features, and after using "Registry Tweak Tool" AKA install_wim_tweak this number grows up to six hundreds. Purpose of most packages and features is clear, but some has pretty obscure names. :-/ Are there any resourses where purpose of packages/features described? I have seen some for Windows 7 but 8.1 has too many new ones. P.S. I have attached the list of packages for Windows 8.1 SL as an example.
