You can uninstall most of the built-in apps - even the ones that don’t normally offer an “Uninstall” option - with a Powershell cmdlet. However, that this trick won’t allow you to remove a few of the most important built-in apps, like Cortana and Microsoft Edge. If you try, you’ll see an error message saying they cannot be removed. 

Notes:  In case you decide you want the bloatware apps back you can install all of them with the following line of PowerShell code: 

Get-AppxPackage -AllUsers| Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"} 

This command tells Windows to install those default apps again. Give it some time and allow it to finish, even if nothing appears to happen at first.
