All Metro Apps on Windows 8.1 Do Not Work

标签：

所有的Metro Apps不能够正常打开，表现为打开后自动最小化到任务栏，并且不能恢复正常状态。在Event Viewer\Application中相应的错误信息为：

Activation of app winstore_cw5n1h2txyewy!Windows.Store failed with error: This app does not support the contract specified or is not installed. See the Microsoft-Windows-TWinUI/Operational log for additional information.

• 如果只是要打开PC Settings，以管理员权限运行命令行：

powershell -ExecutionPolicy Unrestricted Add-AppxPackage -DisableDevelopmentMode -Register $Env:SystemRoot\ImmersiveControlPanel\AppxManifest.xml

• 重新安装所有Metro应用，在PowerShell中执行命令（It performs a complete reinstall of the "metro" apps using the following command in PowerShell to fix the apps minimizing on start:）

Get-AppxPackage | % { Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppxManifest.xml" -verbose }

What it does is this:  Get-AppxPackage gets a list of installed app packages (.appx) and Add-AppxPackage installs an app package. So the command kind of reinstalls metro applications, but with DevelopmentMode disabled. It shouldn‘t be harmful in a sense that it won‘t install anything new or remove existing apps.
