To view installed applications for a particular user, launch an elevated PowerShell prompt and use the command Get-AppxPackage –user username. This should produce a long list of installed “Modern” applications.
To remove Candy Crush, add the parameter –Name king.com.CandyCrushSaga. The parameter to note is the Full Package value.
The cmdlet to remove a “Modern” application is Remove-AppxPackage. If you attempt to use the command still at the elevated prompt, an error will be returned.
If the Remove-AppxPackage cmdlet is used followed by the full package name under the user account name in question, it should be successful.
