Add Store to Windows 10 Enterprise LTSC

For Windows 10 Enterprise LTSC 2019 Download

To install, run Add-Store.cmd as Administrator

If you do not want App Installer / Purchase App / Xbox identity, delete each one appxbundle before running to install. However, if you plan on installing games or any app with in-purchase options, you should include everything.
If the store still will not function, reboot. If still not working, open the command prompt as the administrator and run the following command, then reboot once more.

PowerShell -ExecutionPolicy Unrestricted -Command "& {$manifest = (Get-AppxPackage Microsoft.WindowsStore).InstallLocation + '\AppxManifest.xml' ; Add-AppxPackage -DisableDevelopmentMode -Register $manifest}"
