Windows Server 2012 R2 and Windows 8.1

Updated: October 17, 2013

Applies To: Windows 8.1, Windows PowerShell 4.0, Windows Server 2012 R2

Debug-MMAppPrelaunch

Provides the ability to debug the application prelaunch of a specific application by triggering the prelaunch to occur and to exit debug mode for the application.

Syntax

Parameter Set: Debug0
Debug-MMAppPrelaunch -PackageFullName <String> -PackageRelativeAppId <String> [-AsJob] [-CimSession <CimSession[]> ] [-DisableDebugMode] [-ThrottleLimit <Int32> ] [ <CommonParameters>]




Detailed Description

Prelaunching is a new feature added in Windows® 8.1 that improves the launch performance of apps from the Windows Store by proactively launching frequently used apps in the background if they are not already running or suspended. This makes starting an app as fast as switching to a suspended app from the user’s perspective. This command enables you to prelaunch an app into debug mode.

You identify the application to prelaunch by including the –PackageFullName and -PackageRelativeAppId parameters.

To turn off debugging, specify the application and also include the –DisableDebugMode.

Parameters

-DisableDebugMode

Specifies that debug mode for the selected application is turned off.

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete. The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet. For more information about Windows PowerShell® background jobs, see about_Jobs.

-CimSession<CimSession[]>

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

-ThrottleLimit<Int32>

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

Examples

Example 1: Prelaunch an app and enable debug mode

This command prelaunches an application in debug mode.


PS C:\> Debug-MmAppPreLaunch -PackageFullName Microsoft.ZuneMusic_2.0.94.0_x64__8wekyb3d8bbwe -PackageRelativeAppId Microsoft.ZuneMusic

Example 2: Clear debug mode from the prelaunch activated app

This command disables the debug mode from the app that you previously prelaunch activated.


PS C:\> Debug-MmAppPreLaunch -PackageFullName Microsoft.ZuneMusic_2.0.94.0_x64__8wekyb3d8bbwe -PackageRelativeAppId Microsoft.ZuneMusic -DisableDebugMode

Example 3: Getting the PackageFullName and PackageRelativeAppId of your App

This command shows how you can find the PackageFullName and PackageRelativeAppId information for your package.


PS C:\> ForEach ($Package in Get-AppxPackage) {ForEach ($AppRelativeId in (Get-AppxPackageManifest($Package)).Package.Applications.Application.Id) {'PackageFullName: ' + $Package.PackageFullName; 'PackageRelativeId: ' + $AppRelativeID; ''}}
