But would that give the added bonus of disabling Bing in the start menu?

Nope, not likely.

All was fixed for me by running this Powershell command:

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

Same problem started yesterday (EU time).But solved automatically this morning.
On several webs I had found the following powershell (admin)command as solution:
Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}I had tried it yesterday but it didn't work.
It worked (reinstall/reregister) for most of the built-in app but it gave also for 4 apps an error namely 0x80073D02

I give an example:
---------------------------------------------------------------------------------------------------------------------------------------------
Add-AppxPackage : Deployment failed with HRESULT: 0x80073D02, Het pakket kan niet worden geïnstalleerd omdat bronnen wa arin wijzigingen moeten worden aangebracht, momenteel in gebruik zijn. error 0x80073D02: Unable to install because the following apps need to be closed AppleInc.iTunes_12104.2.43056.0_x64__n zyj5cx40ttqa.

Someone pretends this error can be ignored If you have no problems
