FIX: You’ll need a new app to open this ms-windows-store Error

If you are seeing ‘You’ll need a new app to open this ms-windows-store’ error while opening the Microsoft store in Windows 10, here’s how to fix it.

When you or some app in your system tries to open the Microsoft store in Windows 10, it might fail to open under certain circumstances. When that happens, you might see a strange error saying “You’ll need a new app to open this ms-windows-store”.

What the error is saying is that there is no app on your computer that can open the “ms-windows-store” package. a.k.a, the Microsoft Store. You can think of it as a command to open the Microsoft Store in Windows 10. You will see this kind of error when the store files are corrupted or some other application in your system completely disabled or installed Microsoft store in Windows 10.

For example, if you’ve ever used third-party debloating programs, they might be a bit more aggressive than you think and completely disabled or uninstall the store from Windows 10.

The good thing is, though the error looks strange at first glance, it is pretty easy to fix the problem. All you have to do is reinstall the Windows store. Doing that will bring back the store and fix the ms-windows-store error. Without any delay, let me show you the steps to fix the problem in Windows 10.

Fix “you need a new app to open ms-windows-store” error

To fix the error follow the steps given below.

  1. Right-click on the Start menu.
  2. Select the “Windows PowerShell (Admin)” option. This action will open the PowerShell with admin rights.
  3. If you see a UAC prompt, click on the “Yes” button.
  4. Paste the below command in the PowerShell window and press Enter.
    Get-AppxPackage -allusers Microsoft.WindowsStore | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
  5. Close the PowerShell window after executing the command.
  6. Restart Windows 10 to apply the changes.

After restarting Windows 10, try to open the Windows Store manually. It should open normally. From now on, you can also open the store using other apps without any errors whatsoever.

Though the command words for a vast majority of Windows 10 users, if you see any kind of error, it is highly probable that the files are not available or damaged in such a way that it is not possible to reinstall the store. In that case, follow the second method.

Create a new user account to fix ‘ms-windows-store’ error

If the above method did not work then there is not other way but to create a new user account and migrate to it. The good thing, it is pretty easy to do.

I recommend you first create a local user account, migrate all files in the user directory to your new account and delete the old account. After doing all that in that order, sign in to your Microsoft account in Windows 10, if necessary. That way, you can avoid any unnecessary conflicts between online user accounts in Windows 10.

To create a new user account, open the Settings app, go to the “Accounts → Family & other users” page and click on the “Add someone else to this PC” button. Now, follow the wizard to create a new user account. As I said before, I recommend you create a local user account first and then switch to an online account if necessary.
