4. Alter Permissions in Windows Registry

The next steps underneath will focus on changing certain permissions inside Windows Registry.

Therefore, let’s try to grant them by doing the following:

  1. Press Windows key + R buttons together, type regedit and press Enter to open. Also, confirm the User Account Control (UAC) window if prompted.
  2. On the left pane of Registry Editor, navigate through this path HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppModel\Repository\Packages.
  3. Then, right-click on Packages and select Permissions.
  4. After this, click on Advanced and then Change on top of the window.
  5. It is important to make sure that the Owner is set as System.
  6. If there is no System written in the third box, you have to write it yourself and then click on Check Names.
  7. Once done, click on OK to confirm and move your eyes all the way down to the option called Replace all child object permission entries with inheritable permission entries from this object.
  8. Choose it, click Apply and then OK afterwards to save the assigned changes.

Finally, close the window and restart your PC to check if the issue will get resolved.

5. Use PowerShell to re-register Windows Store

As an alternative to using the WSReset.exe tool, you can also try and perform the same resetting via Windows PowerShell. This will only require you to enter one command, which can be found in the steps below:

  1. Right-click on Start Menu and choose PowerShell (Admin). Click Yes in the UAC window to allow opening.
  2. Once in the PowerShell console, copy-paste this command $manifest = (Get-AppxPackage Microsoft.WindowsStore).InstallLocation + '\AppxManifest.xml' ; Add-AppxPackage -DisableDevelopmentMode -Register $manifest and then press Enter.
  3. Wait until the process ends up complete and reboot your PC to see if something has changed.

6. Reinstall Windows Default Apps

This method is more advanced, and it also involves the usage of Windows PowerShell. Make sure you follow the instructions carefully, performing each step given. Note that this step will reinstall all default Windows apps such as Calendar, Mail, Camera, Photos, and Windows Store as well. Do not worry, your personal files will not be affected in any way during the process.

  1. First, it is important to make sure you can see Hidden items. You can do it by going to This PC, navigating to View on top and then choosing Hidden items.
  2. Once this is done, go to C:\Program Files and locate a folder called WindowsApps.
  3. Right-click on it and choose Properties. Go to Security and then choose Advanced.
  4. Next, we have to change the owner of the key. Click on Change (highlighted in blue).
  5. Then, you have to enter the name of your user account into under the field that says Enter the object name to select and finish by clicking OK.
  6. Now go back to the Security tab of the WindowsApps folder’s Properties window, click on Edit to change permissions and select the personal user account you typed in the steps above. You should also change permissions to Full Control and apply the changes.
  7. The process of reinstalling Windows Apps is not completed yet, this was only the preliminary stage where we set things up for the reinstallation itself. Here is what you should do next:

  8. Open PowerShell (Admin) the same way we did in the previous method.
  9. Then, copy-paste this command Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register $($_.InstallLocation)\AppXManifest.xml} and press Enter to initiate.
  10. Once done, reboot your computer and see if something has changed to the positive side.

7. Create a new user account

Sometimes creating a new account may also aid in rectifying the issue. A new account means it will operate from scratch with zero modifications made, including those related to permissions.

  1. Right-click on the Start Menu button and choose Settings. You can also do it with Windows key + I combination.
  2. Go to Accounts > Family & other users.
  3. On the right pane, scroll down to the Other users section and click Add someone else to this PC.
  4. Now choose I don’t have this person’s sign-in information.
  5. Select Add a user without a Microsoft account.
  6. Then enter the username and password for the new user and click Next.
