Error HRESULT 0x80073CFA in Windows 10 while Uninstalling Universal Apps



If you have ever wanted to uninstall bloatware from Windows 10, which of course, you should, chances are that you may not have fully succeeded in that task.HRESULT 0x80073CFA

Some apps can be uninstalled. But, for some (and that list is increasing), you will get the error:

HRESULT: 0x80073CFA, Removal failed. Please contact your software vendor

Case in point: HolographicFirstRun, which comes preinstalled in Windows 10 with no option of removal. And, there are many apps like this.

If you are wondering why; well, this app is a part of Windows 10’s basic functionality, so they are deliberately made as such by Microsoft.

This was not always the case though. Starting from the Anniversary Update, Microsoft has added the IsInbox label in their app repository database.

Here is a list of apps that you should not try removing:

  • WindowsFeedback
  • MicrosoftEdge
  • ContactSupport
  • CloudExperienceHost
  • ParentalControls
  • Xbox[GameCallableUI/IdentityProvider]
  • Cortana

Any app labeled with the IsInbox, failed to uninstall with the code 0x80073CFA.

There is a way to remove these apps, but I would actually ask you to not proceed with removing them. The workaround for uninstalling them is a little ugly and terse for my liking.

Regardless, if you understand what you are doing, here are the instructions to fix the error 0x80073CFA, Removal failed. Please contact your software vendor.

A used named Fifteen15Studios has found a PowerShell script which can remove all the unwanted apps from your PC.
