Uninstall it, as listed here:
In elevated powershell, search for the PackageFullName... and then Remove that package:
Get-AppxPackage | Select Name, PackageFullName
Remove-AppxPackage Microsoft.Windows.Cortana_1.4.8.176_neutral_neutral_cw5n1h2txyewy
I'm using the same uninstall to remove other "features" like BingNews, BingSports, Etc
Likewise, you can remove the "Provisioned" applications (aka: crap that gets installed during user creation) via this method
Get-AppxProvisionedPackage -Online | Select DisplayName, PackageName
Remove-AppxProvisionedPackage Microsoft.ZuneMusic_2019.6.11821.0_neutral_~_8wekyb3d8bbwe
Or... to remove ALL Apps that you can, app or provisionedapp, you can do this:
Just a warning: This will uninstall the Windows Store. That's not an issue for me, but uninstalling everything isn't for the faint of heart.
Get-AppxPackage | Remove-AppxPackage
Get-AppxProvisionedPackage -Online | Remove-AppxProvisionedPackage -online
It's probably wise not to completely remove the windows store. This (in the comments) looks to be ballpark of what I'd use:
Get-AppxPackage -AllUsers | where-object {$_.name –notlike “*store*”} | Remove-AppxPackage
Get-appxprovisionedpackage –online | where-object {$_.packagename –notlike “*store*”} | Remove-AppxProvisionedPackage -online
