Hi,
If you want to uninstall store application, we could run the following command line as administrator in PowerShell.
Get-AppxPackage -allusers packagename | Remove-AppxPackage
If you not know the exact name of appxpackage, we could use the following command to query.
Get-AppxPackage -AllUsers
But for services, I would not recommend to uninstall or disabled them, as they would affect system usage such as BthAvctpSvc which is used to protect user files from accidental loss by copying them to a backup location. Yet for MapsBroker and TrkWks, which are not used for general system usage, could be deleted without an issue.
As there is not a services list ranking by security level released by Microsoft, so it would be difficult to say which should be removed.
Bests,
