If, like I, you are sure you won’t need those pesky apps, use the following PowerShell pipeline to get rid of the provisioned packages:
Get-AppxProvisionedPackage -Online|Out-GridView -PassThru|Remove-AppxProvisionedPackage -ErrorAction Continue -Online
… to also remove those apps that are marked removable, use the following:
Get-AppxPackage -Allusers|Where-Object {!$_.NonRemovable}|Out-GridView -PassThru|Remove-AppxPackage -ErrorAction SilentlyContinue -AllUsers
These two commands will present you with a grid view to select whatever packages you want removed. Start these inside a privileged PowerShell for full effect.
Note that on Windows 10 even simple apps like the calculator are Metro apps and therefore will be missing if you select them for removal. Not that you will necessarily miss such apps a lot, just saying …
