MiracastView package causes sysprep error after you upgrade a computer to Windows 10 Version 1709

This article provides workarounds to an issue in which sysprep fails with an error after you upgrade a computer to Windows 10 Version 1709.

Applies to: Windows 10, version 1709
Original KB number: 4057974

Symptoms

Consider the following scenario:

On a Windows 10 Version 1703 based computer, MiracastView is a built-in app and is installed by default.
You upgrade the computer to Windows 10 Version 1709.
You open a Command Prompt window with administrator permission and run the following command:
```
cd %windir%\System32\Sysprep
sysprep.exe /generalize /oobe /reboot
```

In this scenario, the sysprep command fails. You receive an error message that resembles the following:

Sysprep was not able to validate your Windows installation. Review the log file at %WINDIR%\System32\Sysprep\Panther\setupact.log for details. After resolving the issue, use Sysprep to validate your installation again.

Additionally, the setupact log contains error messages that resemble the following:

Date/Time, Error SYSPRP Package Windows.MiracastView_6.3.0.0_neutral_neutral_cw5n1h2txyewy was installed for a user, but not provisioned for all users. This package will not function properly in the sysprep image.
Date/Time, Error SYSPRP Failed to remove apps for the current user: 0x80073cf2.
Date/Time, Error SYSPRP Exit code of RemoveAllApps thread was 0x3cf2.
Date/Time, Error SYSPRP ActionPlatform::LaunchModule: Failure occurred while executing 'SysprepGeneralizeValidate' from C:\Windows\System32\AppxSysprep.dll; dwRet = 0x3cf2
Date/Time, Error SYSPRP SysprepSession::Validate: Error in validating actions from C:\Windows\System32\Sysprep\ActionFiles\Generalize.xml; dwRet = 0x3cf2R

When you use the Remove-AppxPackage PowerShell command to remove MiracastView, the command does not work, and you receive the following error message:

Deployment Remove operation with target volume C: on Package Windows.MiracastView_6.3.0.0_neutral_neutral_cw5n1h2txyewy from: failed with error 0x80070490.
See http://go.microsoft.com/fwlink/?LinkId=235160 for help diagnosing app deployment issues.

(Screenshot in the original article: The error message that occurs when you use Remove-AppxPackage to remove MiracastView.)

Cause

This issue occurs due to a bug in the way setup migrated the Windows.MiracastView_6.3.0.0_neutral_neutral_cw5n1h2txyewy package during the upgrade. This package will not function properly in the generalized image.

Workaround

To work around this issue, use either of the following methods.

Method 1

On the Windows 10 Version 1709 computer, copy Windows.MiracastView_6.3.0.0_neutral_neutral_cw5n1h2txyewy.xml from C:\Windows.old\ProgramData\Microsoft\Windows\AppRepository\ to C:\ProgramData\Microsoft\Windows\AppRepository.

Method 2

Copy the C:\Windows\MiracastView folder from a Windows 10 Version 1703 computer to the Windows 10 Version 1709 computer. Then, restart the computer to let Windows finish uninstalling MiracastView.
