    • Got the same problem here...
      I got the Version of 19.06.2015, but if I try .\Convert-WindowsImage.ps1 -ShowUI  it won't show anything. Just root.
      Then I tried the advise of Cesar de la Torre, but then I get same error like DJYeo.
      In my case I try to convert a Win10 ISO to a vhd with fixed size for Azure.
      Could someone help me please?
    • Hi,
      There is a small snag in the code. Search for "$script:SourcePath" and replace it with "$SourcePath".
      Make sure to dot source again the script to update the function in your console.
    • Additionaly to the post before - success with the change - this change seems to be also necessary
    • I have to recall ==> the change helped, but stil no success
      ERROR  : No source path specified.
      Gui is working and with replacement of the variable I can choose an ISO Image, but not able to convert

    • I've been trying to get this to work with a sysprepped corporate image we use.  I kept getting the "The variable cannot be validated because the value  is not a valid value for the Edition variable."  It's the only image in the .wim, and Edition 1 wasn't working.  It was dying on line 4077 when it tried to open the image.  The ImageName in the .wim was "Windows", so I just hard coded the $Edition variable to "Windows" and it worked.  Don't know if this will help anyone or not.

    • Hi I'm running the following command
      .\Convert-WindowsImage.ps1 -WIM .\NanoServer\NanoServer.wim -Size 10GB -VHDFormat VHD -Edition 1
      And nothing happens. It still Works fine with the previus version.
      Any suggestions ?
    • Open the script with PoewrShell ISE rather than plain Powershell, and as admin.
      you´ll see the function in the editor.
      Scroll down, and write the call to the function right at the end, after the function as:
      Convert-WindowsImage -ShowUI
      Execute the whole script within PowerShell ISE. You´ll see the UI Windows, etc.

  • Скрипт не распознаёт ISO-образ
    4 Posts | Last post June 25, 2015
    • Если версия скрипта Convert-WindowsImage.ps1 от 19.06.2015 у вас не запускается, как это показано в видео Игоря (, то необходимо его запускать так:
      1) . .\Convert-WindowsImage -ShowUI
      2) Convert-WindowsImage -ShowUI
      Но я столкнулся с другой проблемой, которую можно увидеть на данном скриншоте: — ошибка эта появляется после того как я выбираю ISO образ, который скачан с официальной страницы MS.
    • If script don't run, try (without .sp1):
      1). .\Convert-WindowsImage -ShowUI 
      2)Convert-WindowsImage -ShowUI 
      For me works only 2)Convert-WindowsImage -ShowUI
    • You can use Step-by-step guide from here:
      Hope it helps
    • This is what you need to do:
      Copy the files to a directory on your hard drive.
      Launch PowerShell.   I usually launch a CMD in administrative mode then I run powershell.
      go tot he directory where you copy the files.
      Run . .\Convert-WindowsImage.ps1
      Make sure that between the dots there is a space. That will load it as a function.
      Now when you run the script to create you VHD, make sure there are no dots or back slashes.   To create the VHD from the nanoserver folder, this is the command.
      Convert-WindowsImage -Sourcepath c:\nanoserver\NanoServer.wim -VHD c:\Nanoserver\nanoserver.vhd –VHDformat VHD -Edition 1
      As you can see, the command has no .\ in it.
  • Failure with Nanoserver

    • Running this on Windows 8.1 to build VHD for nanoserver failed with the message:
      ERROR  : Cannot convert the "System.String[]" value of type "System.String[]" to type "System.Int32".
      The command used was:
      Convert-WindowsImage -WIM d:\software\Microsoft\Windows\nanoserver\NanoServer\NanoServer.wim -VHD d:\software\Microsoft\Windows\nanoserver\NanoServer.vhd -DiskType Fixed -VHDFormat VHD -SizeBytes 10GB -Edition 1
      I tracked this down with the debugger and fixed it by changing line 4092 to:
      $openImage = $openWim[[Int32]::Parse($Edition)]

    • hello all

      any help please
    • The script is now a function. you have to ". .\ Convert-WindowsImage.ps1" first, then run the command (without .ps1).
  • Windows 10 is not properly detected
    3 Posts | Last post May 31, 2015
    • When running the script on Windows 10 - 10074 the scripts doesn't validate properly the version of the operating system
      This is the problematic part: 
      Function Test-WindowsVersion {
              $os = Get-WmiObject -Class Win32_OperatingSystem 
              $isWin8 = (($os.Version -ge 6.2) -and ($os.BuildNumber -ge $lowestSupportedBuild))
              Write-W2VTrace "isWindows8? $isWin8"
              return $isWin8
      This is what happens
      PS C:\Users\josefern\Downloads> $os
      SystemDirectory : C:\WINDOWS\system32
      Organization    : Microsoft IT
      BuildNumber     : 10074
      RegisteredUser  : Microsoft Corp.
      SerialNumber    : 00261-30000-00000-AA291
      Version         : 10.0.10074
      PS C:\Users\josefern\Downloads> $os.Version -ge 6.2
      PS C:\Users\josefern\Downloads> $os.BuildNumber -ge $lowestSupportedBuild
    • This is an issue that turned out once build numbers passed 10000. They are actually returned as strings, not integer values. This means 10074 is actually less than 9200 (because it starts with a 1, compared to a 9).
      Easiest way here: correct the line to
      $isWin8 = $true
      More elegant way: 
      $isWin8 = (($os.Version -ge 6.2) -and ([int]$os.BuildNumber -ge [int]$lowestSupportedBuild))
      Untested yet, but should work.
    • The fix doesn't quite work because the ($os.Version -ge 6.2) test also fails. Implicit Casting $os.version to float throws an error. This works though:
      $isWin8 = (([float]($os.Version.Split('.')[0]+'.'+$os.Version.Split('.')[1]) -ge 6.2) -and ([int]$os.BuildNumber -ge [int]$lowestSupportedBuild))
      I've tried this on Windows 10, Windows 8.1 and faked it on Windows 7 to ensure it returns false. There are probably nicer ways of doing this.

  • failes on custom WIM files

    • This fails on any image created with
      New-WindowsImage -CapturePath C:\VHDMount -Name MyImage -ImagePath C:\CapturedWIMs\2012r2.wim -Description “MyCustomeImage” -Verify
      If I comment out lines 4021-4024 and line 4038 and supply -Edition 1 then it works.
