I wanted to mount an image but I got the following error:
Mount-WindowsImage : DismInitialize failed. Error code = 0xc0040009 At line:1 char:1 + Mount-WindowsImage -Path D:\MountedImage -ImagePath D:\sources\2019\b ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (:) [Mount-WindowsImage], COMException + FullyQualifiedErrorId : Microsoft.Dism.Commands.MountWindowsImageCommand
This was due to the fact that the file was read-only (which is usually the case when you copy it from a CD/DVD to a hard drive).
An easy way to set file attributes is to use the
Normaly, there is no need to have any attribute on this file. So you can set it to Normal.
Set-ItemProperty -Path D:\Sources\2019\boot.wim -Name Attributes -Value Normal
