Hi guys, I have a problem with my AIO ISO. When I use it to do an upgrade from Windows 7 and Windows 8.x, W10 is NEVER activated after update. Of course I'm using the same version (W7 Ultimate 64 to W10 Pro 64 and W8.1 Core 86 to W10 Home 86) and Windows licenses are official. I have the error code "0xc004c003" as a lot of people... (Key is blocked). Windows Store tells me the license is not official and wants me to buy a new one. - slmgr /ato never works. - slmgr /dlv indicates "0xc004f034" for "Notification Reason" (which sounds better than "0xc004c003"). With a DVD created with MediaCreationTool it works. Does someone have the same problem (I hope so...) ? Thanks .
