Hi! So subject is the question: how can I skip entering product key completely? My iso is Windows 10 Multiple Editions (original MSDN). There are two times when I have to enter product key: during initial phase of setup (where it's impossible to continue without key - if no changes made to ei.cfg), or after setup (where there is a button "do it later)". I am able to skip the first one, but no matter what I do it asks me the key after setup. Of course I can skip it by pressing a button, but at this point the "unattended" setup becomes not so unattended: I have to use my hands to press something What I want: not to ask me to enter the key both times. Disclaimer: for testing purposes What I have tried: - editing ei.cfg, that helps skipping entering the key at the early stage. - putting <ProductKey></ProductKey> (empty value) in autounattend.xml in <settings pass="specialize">: setup results with error. According to M$ (unfortunately I can't post links): "If you specify a product key in the windowsPE configuration pass with ProductKey (Microsoft-Windows-Setup), then Windows Welcome will prompt for a product key. If you specify the ProductKey (Microsoft-Windows-Shell-Setup) setting during the specialize pass, then Windows Welcome will not prompt for a product key." I have multiple editions iso, so hardcoding one specific key in autounattend.xml is not an option for me. Thatswhy there is an empty value. - inserting key in oobe.cmd with slmgr.vbs -ipk %needed-generic-key-depending-on-edition%: setup still is asking me key at the end of install. And at this point I am out of ideas... Anyone help?
