Scripting

I get rid of mine as a post install task in the installation.

write list of apps needed for uninstall in a text file.....save as a PowerShell script  (PS1)

call it "RemoveApps.ps1" or whatever else you like.

It should have all the apps you want to remove listed as below for example

Get-AppxPackage *3dbuilder* | Remove-AppxPackage
Get-AppxPackage *windowscamera* | Remove-AppxPackage
Get-AppxPackage *CandyCrushSaga* | Remove-AppxPackage
Get-AppxPackage *officehub* | Remove-AppxPackage
Get-AppxPackage *skypeapp* | Remove-AppxPackage

then create a bat file called "uninstall.bat" or any other name with the command...

powershell.exe -executionPolicy bypass -file RemoveAppsFinal.ps1

Zip these two up and upload to the k2  in a post install task.

(don't zip the folder they are in......just the two files)

In the "Full command line" box call the bat file..

uninstall.bat

cleans all the apps I don't need.

You need to get rid for All Users, you need to use -AllUsers

See below

Function RemMostApps {
        Write-Host "***Removing all apps and provisioned appx packages for this machine except Photos,Calculator...***"     
        Get-AppxPackage -AllUsers | where-object {$_.name -notlike "*Microsoft.Net.Native*" -and $_.name -notlike "*Calculator*" -and $_.name -notlike "*sticky*" -and $_.name -notlike "*Windows.Photos*" -and $_.name -notlike "*SoundRecorder*" -and $_.name -notlike "*MSPaint*"} | Remove-AppxPackage -erroraction silentlycontinue
        Get-AppxPackage -AllUsers | where-object {$_.name -notlike "*Microsoft.Net.Native*" -and $_.name -notlike "*Microsoft.VCLibs*" -and $_.name -notlike "*Calculator*" -and $_.name -notlike "*sticky*" -and $_.name -notlike "*Windows.Photos*" -and $_.name -notlike "*SoundRecorder*" -and $_.name -notlike "*MSPaint*"} | Remove-AppxPackage -erroraction silentlycontinue
        Get-AppxProvisionedPackage -online | where-object {$_.displayname -notlike "*Microsoft.Net.Native*" -and $_.displayname -notlike "*Microsoft.VCLibs*" -and $_.displayname -notlike "*Calculator*" -and $_.displayname -notlike "*sticky*" -and $_.displayname -notlike "*Windows.Photos*" -and $_.displayname -notlike "*SoundRecorder*" -and $_.displayname -notlike "*Netflix*" -and $_.displayname -notlike "*MSPaint*"} | Remove-AppxProvisionedPackage -online -erroraction silentlycontinue      
}   

RemMostApps

This gets rid of everything apart from Netflix I think.  I do not recommend getting rid of the store though.

Once it runs, when you login as the New User it will have cleaned up all the apps.
