After you have mounted your WIM file, you can display the list of provisioned Microsoft Store app packages. I have used a more convenient text file format to view the command output:

Dism.exe /image:c:\mount /Get-ProvisionedAppxPackages > c:\ps\apps.txt

The information about each app will look like this:

DisplayName : Microsoft.BingWeather
Version : 4.25.20211.0
Architecture : neutral
ResourceId : ~
PackageName : Microsoft.BingWeather_4.25.20211.0_neutral_~_8wekyb3d8bbwe

Now it’s time for the most interesting things: we will remove all apps we don’t need. Unfortunately, apps like Edge, Cortana, Contact Support and some others cannot be removed (but you can disable them using GPO). I also recommend to leave the calculator (Microsoft.WindowsCalculator), photo viewer (Microsoft.Windows.Photos), Microsoft.VP9VideoExtensions, since new builds of Windows 10 don’t have classic (desktop) versions of these apps. Also, don’t remove the Microsoft.WindowsStore, because it is hard to restore it if you need it one day.

You can remove apps one-by-one or all at once. To remove a modern app from the mounted image, specify its name (PackageName). Let’s remove the BingWeather app:

dism.exe /image:c:\mount /Remove-ProvisionedAppxPackage /PackageName:Microsoft.BingWeather_4.25.20211.0_neutral_~_8wekyb3d8bbwe

In the same way, remove all built-in apps you do not need.

When you are done, unmount the image and save the changes (see below how to do it).

Also, you can remove preinstalled apps from the Windows 10 installation image using a ready-made PowerShell script from the TechNet Gallery : https://gallery.technet.microsoft.com/Removing-Built-in-apps-65dc387b.

An advantage of this method is that you don’t need to mount the wim file manually. All you have to do is to specify a path to the .wim file and run the PowerShell script. However, if something goes wrong, it will be harder to find an error no matter whether it is related to DISM or the script itself.

Open PowerShell as an administrator and run the following command:

.\removeapps.ps1 -pathtowim c:\Windows10\sources\install.wim -selectapps $true

You will see each app in a separate line and you can select whether to remove (Y) or leave (N) it.

After you select an action for all of the apps, the script will remove those you don’t need. Unlike DISM, you don’t need to save changes to the .wim file — they will be saved by the script.

If you want to remove all apps, remove the parameter selectapps $true in the end of the command. This will remove all applications that can be removed.

When working with PowerShell, you might get an error because the current execution policy settings don’t allow PowerShell scripts to run.

To fix it, run this PowerShell command and change the Execution policy settings:

Set-ExecutionPolicy -ExecutionPolicy Unrestricted

This will allow PS1 scripts to run on.

Disable or Remove Capabilities & Features from a Windows 10 Install Image

You can use DISM to remove (or install) certain features from your Windows 10 installation image.

Get the list of preinstalled components in the mounted Windows 10 installation image using DISM:

Dism.exe /image:c:\mount /Get-Capabilities

A component may be installed or disabled (Not Present).

You can also display a list of all Windows components in the image using PowerShell (in this example, we will display only the installed Windows components):

Get-WindowsCapability -Path c:\mount|?{$_.State -eq "Installed"}

Windows 10 1909 has the following components preinstalled:

App.Support.QuickAssist~~~~0.0.1.0
Browser.InternetExplorer~~~~0.0.11.0
Hello.Face.18330~~~~0.0.1.0
Hello.Face.Migration.18330~~~~0.0.1.0
Language.Basic~~~en-US~0.0.1.0
Language.Handwriting~~~en-US~0.0.1.0
Language.OCR~~~en-US~0.0.1.0
MathRecognizer~~~~0.0.1.0
Media.WindowsMediaPlayer~~~~0.0.12.0
OneCoreUAP.OneSync~~~~0.0.1.0
OpenSSH.Client~~~~0.0.1.0

You can remove an installed component by its name. Let’s remove a face recognition component Hello.Face:

Dism.exe /image:c:\mount/Remove-Capability /CapabilityName:Hello.Face.18330~~~~0.0.1.0

Also, you can enable some of capabilities in the image. For example, to install all RSAT administrative tools:

Get-WindowsCapability -Path c:\mount |? {$_.Name -like "*RSAT*" -and $_.State -eq "NotPresent"} | Add-WindowsCapability -Path c:\mount

In the same way, you can enable/disable other components. For example, let’s enable .NET 3.5 and disable SMB1:

dism.exe /image:C:\mount /enable-feature /featurename:netfx3 /all /source:E:\sources\sxs
dism.exe /image:C:\mount /disable-feature /featurename:smb1protocol

In the same way, you can integrate drivers or latest security updates to your Windows 10 install image.

Optimizing the Windows 10 WIM Installation Image

After you have made changes to your Windows 10 install image, optimize and clean it using the /cleanup-image parameter.

Remove previous component versions using the /ResetBase option:

Dism /Image:C:\Mount /cleanup-image /StartComponentCleanup /ResetBase

Check the image for errors using?Dism /ScanHealth.

DISM /Image:C:\Mount /Cleanup-Image /ScanHealth

It remains to unmount the image and save the changes to the WIM file:

dism.exe /unmount-wim /mountdir:c:\mount /commit

If you have changed your mind, use the /discard parameter instead of /commit to discard changes.

To save space, you can additionally compress install.wim to install.esd using the command:

Dism /Export-Image /SourceImageFile:c:\iso\install.wim /SourceIndex:1 /DestinationImageFile:c:\iso\install.esd /Compress:recovery

Then copy your install.wim (install.esd) to your Windows install media. You should only copy the .wim file and not update any other files.

To create an ISO image from you install files, you may use a free portable program Folder2ISO or other similar programs.
