If you decide you want the preinstalled apps back, you can reinstall them with a single line of PowerShell code. Again, open a PowerShell window as Administrator. Copy and paste the following line at the PowerShell prompt, and then press Enter:
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. Even if you see an error message, restart your PC, and then examine your Start menu—you may just have all those default apps back again, anyway.
Again, the only real advantage to doing this is some mild decluttering of your Start menu. It's also likely that future updates (especially major updates) could reinstall those apps.
