1. Use the esd-decrypter-v4c to decrypt the esd-file.esd 2. Copy a install.wim from other place such as a Windows 8 installation disk. Put it in some place such as d:\install.wim 3. Use dism /get-wiminfo /wimfile:\install.wim to check the existing image in the wim file 4. You can't use dism /Export-Image to export a esd file to a wim file directly. However, you can export it to a existing wim file as a image. That's why I make a copy of a install.wim dism /Export-Image /SourceImageFile:esd-file.esd /SourceIndex:4 /DestinationImageFile:\install.wim /compress:max /CheckIntegrity 5. Now dism /get-wiminfo /wimfile:\install.wim to check the wim file and you will be able to find there is a new index(image). Remember the index number. 6. Use dism command to export the image in the d:\install.wim to a new file. dism /Export-Image /SourceImageFile:\install.wim /SourceIndex:2 /DestinationImageFile:\final-install.wim /compress:max /CheckIntegrity Note: Adjust the SourceIndex here accordingly.
