Fixing Windows 10 Apps that Won't Launch or that Hang on the App's Splash Screen

If you've installed Windows 10 Build 9926 and find that some apps work and some apps don't, the fix could be as easy as registering the apps. In particular, some early testers have found that apps like Cortana, the beta Store, and others either won't launch at all, or start to launch but hang on the app's splash screen.

The potential fix goes back to similar issues experienced during earlier Builds, which includes executing a PowerShell command at an elevated command prompt.

The PowerShell command:

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml"}
