Cause

DISM thinks you’re running Windows PE

Apparently, the DISM tool thinks that you’re using it from the Windows Preinstallation Environment (Windows PE) or Windows Recovery Environment (Windows RE), whereas you may be running the tool on a running operating system. The presence of the following registry key causes Windows to think that you’re running Windows PE.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\MiniNT

Windows PE is a standalone preinstallation environment and is an integral component of other setup and recovery technologies, such as Setup for Windows, Windows Deployment Services (Windows DS), the Windows Recovery Environment (Windows RE), etc.

The “MiniNT” key doesn’t exist by default when you install Windows. As for how the key ended up on your registry, it’s possible that you (or a third-party program) have applied the following registry tweak in an attempt to enable ReFS file system format.



[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\MiniNT]
"AllowRefsFormatOverNonmirrorVolume"=dword:00000001

Resilient File System (ReFS) is a Microsoft proprietary file system with the intent of becoming the “next generation” file system after NTFS. You can read more on that in Microsoft Docs post Resilient File System (ReFS) overview.

Or it may have the following entries:

"DoNotCreatePagefile"=dword:00000001
"MaxPageFileUsage"=dword:00000000
"CrashDumpEnabled"=dword:00000000
"AutoReboot"=dword:00000000
"KernelDumpOnly"=dword:00000000
"WriteDebugInfo"=dword:00000000

Please note that the MiniNT key and those registry values don’t exist in a standard Windows installation.

Resolution

To fix DISM Error: 50 “DISM does not support servicing Windows PE” and Error: 87 “The cleanup-image option is unknown”, delete the MiniNT registry key using these steps:

    1. Right-click Start, click Run.
    2. Type regedit.exe and click OK.
    3. Navigate to the following registry key:
      HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\MiniNT

      dism error 50 MiniNT Windows PE key

    4. Right-click MiniNT, and choose Delete
    5. Exit the Registry Editor.
    6. No restart is required, usually. See if you can run DISM now.

This fixes DISM Errors 50 and 87 on Windows 10 and 11, respectively.

Note that the DISM error 87 has multiple causes and the “MiniNT” key is just one of those causes. The DISM log needs to be analyzed to find the reason for the DISM error code 87.
