Here's an example of using the -AddPackage parameter:

msixmgr.exe -AddPackage "C:\MSIX\myapp.msix"

-RemovePackage

Remove the package with specified package full name.

-RemovePackage <Package name>

-x <Package name>

Here's an example of using the -RemovePackage parameter. You can find the package full name by running the PowerShell cmdlet Get-AppxPackage.

msixmgr.exe -RemovePackage myapp_0.0.0.1_x64__8wekyb3d8bbwe

-FindPackage

Find a package with specific package full name.

-FindPackage <Package name>

Here's an example of using the -FindPackage parameter. You can find the package full name by running the PowerShell cmdlet Get-AppxPackage.

msixmgr.exe -FindPackage myapp_0.0.0.1_x64__8wekyb3d8bbwe

-ApplyACLs

Apply ACLs to a package folder (an unpacked package). You also need to specify the following required subparameters:

Required parameter	Description
`-packagePath`	The path to the package to unpack OR the path to a directory containing multiple packages to unpack

-ApplyACLs -packagePath <Path to the package folder>

Here's an example of using the -ApplyACLs parameter:

msixmgr.exe -ApplyACLs -packagePath "C:\MSIX\myapp_0.0.0.1_x64__8wekyb3d8bbwe"

-Unpack

Unpack a package in one of the file formats .appx, .msix, .appxbundle, or .msixbundle, and extract its contents to a folder. You also need to specify the following required subparameters:

Required parameter	Description
`-destination`	The directory to place the resulting package folder(s) in.
`-fileType`	The type of file to unpack packages to. Valid file types include `.vhd`, `.vhdx`, `.cim`. This parameter is only required when unpacking to CIM files.
`-packagePath`	The path to the package to unpack OR the path to a directory containing multiple packages to unpack.
`-rootDirectory`	Specifies root directory on image to unpack packages to. This parameter is only required when unpacking to new and existing CIM files.

-Unpack -packagePath <Path to package to unpack OR path to a directory containing multiple packages to unpack> -destination <Directory to place the resulting package folder(s) in> -fileType <VHD | VHDX | CIM> -rootDirectory <Root directory on image to unpack packages to>

Here's some examples of using the -Unpack parameter:

To unpack a package into a directory:

msixmgr.exe -Unpack -packagePath "C:\MSIX\myapp.msix" -destination "C:\Apps\myapp"

To unpack a package into a VHDX disk image:

msixmgr.exe -Unpack -packagePath "C:\MSIX\myapp.msix" -destination "C:\Apps\myapp\myapp.vhdx" -applyACLs -create -filetype VHDX -rootDirectory apps

To unpack a package into a CIM disk image:

msixmgr.exe -Unpack -packagePath "C:\MSIX\myapp.msix" -destination "C:\Apps\myapp\myapp.cim" -applyACLs -create -filetype CIM -rootDirectory apps

Here are the optional parameters you can use with the -Unpack parameter:

Optional parameter	Description	Example
`-applyACLs`	Applies ACLs to the resulting package folder(s) and their parent folder.	`msixmgr.exe -Unpack -packagePath "C:\MSIX\myapp.msix" -destination "C:\Apps\myapp" -applyACLs`
`-create`	Creates a new image with the specified file type and unpacks the packages to that image. Requires the `-filetype` parameter.	`msixmgr.exe -Unpack -packagePath "C:\MSIX\myapp.msix" -destination "C:\Apps\myapp" -applyACLs -create -fileType VHDX`
`-fileType`	The type of file to unpack packages to. Valid file types include `VHD`, `VHDX`, `CIM`. This parameter is required when unpacking to CIM files. Requires the `-create` parameter.	`msixmgr.exe -Unpack -packagePath "C:\MSIX\myapp.msix" -destination "C:\Apps\myapp" -applyACLs -create -fileType CIM -rootDirectory apps`
`-rootDirectory`	Specifies the root directory on image to unpack packages to. This parameter is required when unpacking to new and existing CIM files.	`msixmgr.exe -Unpack -packagePath "C:\MSIX\myapp.msix" -destination "C:\Apps\myapp" -applyACLs -create -filetype CIM -rootDirectory apps`
`-validateSignature`	Validates a package's signature file before unpacking package. This parameter requires that the package's certificate is installed on the machine. For more information, see Certificate Stores.	`msixmgr.exe -Unpack -packagePath "C:\MSIX\myapp.msix" -destination "C:\Apps\Myapp" -validateSignature -applyACLs`
`-vhdSize`	The desired size of the `.vhd` or `.vhdx` file in MB. Must be between 5 MB and 2040000 MB. Use only for `.vhd` or `.vhdx` files. Requires the `-create` and `-filetype` parameters.	`msixmgr.exe -Unpack -packagePath "C:\MSIX\myapp.msix" -destination "C:\Apps\myapp" -create -fileType VHDX -vhdSize 500`
