Hi, Some odd behaviour of Win 8.1 (64 bit) system. When trying to run PC Settings (immersive control panel) it appears for a second and minimizes. It logs an error event that Windows.Launch contract failed to start the app. I looked on the Internet and as suggested I ran this command elevated Code: C:\Windows\system32>powershell -ExecutionPolicy Unrestricted Add-AppxPackage -Di sableDevelopmentMode -Register $Env:SystemRoot\ImmersiveControlPanel\AppxManifes t.xml Add-AppxPackage : Deployment failed with HRESULT: 0x80073CF6, Package could not be registered. error 0x8007007E: Failed to load the extension DLL due to the following error: The specified module could not be found. . NOTE: For additional information, look for [ActivityId] 88d52d8d-8a30-0000-7434-d588308ad501 in the Event Log or use the command line Get-AppxLog -ActivityID 88d52d8d-8a30-0000-7434-d588308ad501 At line:1 char:1 + Add-AppxPackage -DisableDevelopmentMode -Register $Env:SystemRoot\Imm ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : WriteError: (C:\Windows\Imme...ppxManifest.xml:S tring) [Add-AppxPackage], IOException + FullyQualifiedErrorId : DeploymentError,Microsoft.Windows.Appx.PackageMa nager.Commands.AddAppxPackageCommand As Command prompt suggested, I went on to look for additional information, I got this: Code: Time ID Message ---- -- ------- 24-10-2019 11:42:03 301 The calling process is C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe 24-10-2019 11:42:03 603 Started deployment Register operation on a package with main parameter: file:///C:/Windows/ImmersiveControlPanel/AppxManifest.xml and Options: 0.

I understand I have files missing from system32 folder but that is intentional. I just want to be able to locate the file that's preventing me to use the Immersive Control Panel so I can put it back. Any help will be greatly appreciated.
