This particular method consists of quite a lot of steps and it can help you deal with your Windows Store error efficiently along with some of the side effects which usually follow this error, such as the Start menu not working like it should and similar.

Follow the instructions below carefully and make sure you don’t do something you weren’t supposed to do.

  1. Turn your PC on and log into the administrator account you usually use as the owner of the computer. If you are not the owner of the computer or if you don’t have administrator privileges, please consult with the real owner of the computer or follow the instructions from below this solution in order to create it.
  2. Navigate to the following location on your main hard drive or disk partition:

C: Users AppData Local Packages

 

  1. Delete everything you find in these folders and try to ignore the error messages some of the files you choose may throw at your.
  2. Use the Ctrl + Shift + Esc key combination in order to open the Task Manager. You can also use Ctrl + Alt + Delete and choose if from a list of options or you can simply search for it in the Start menu.
  3. If this is your first time trying to view all of the processes located on your computer, you may need to click on the More details option located at the bottom of the Task Manager windows.

  1. End the following two processes in this exact order by right-clicking on them and choosing the End task option from the context menu:

Windows Shell Experience Host
Windows Explorer
(the taskbar, start menu, desktop icons, etc, will disappear and you shouldn’t be alarmed because of this as this is standard and expected behavior.)

 

  1. Navigate back to the same location displayed below and try to delete everything you locate in the folder. You should be able to delete all of the files; even the ones you weren’t allow to delete in the beginning of the solution.

C: Users AppData Local Packages

  1. If you succeed, you will be able to remove everything except Cortana.
  2. This next step will require you to be quick in its operation as you will need to end the Cortana process quickly and delete its folder (the one which remained in the Packages folder) before the process restarts itself automatically. Skipping this particular step may result in a successful process which will solve your problem but the solution genuinely works as a whole. You can try both ways and check which one works the best.
  3. Once you have finished working on the Packages folder, you should notice that the folder is empty. This means that the process has been successful.
  4. Once the Packages folder is empty, right-click on your Start menu and choose the Windows PowerShell (Admin) option or search for it in the Start menu.

  1. Copy and paste the following command in the administrative PowerShell prompt. Make sure you click Enter afterwards in order to run the command. If the command gets stuck, run it several time one after another until the process ends with success.

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)AppXManifest.xml”}

Since most of the steps we have mentioned can be simplified if you used an administrator account (the steps can be undertaken with an ordinary local account), you should use an administrator account provided by the owner of the computer. However, for the purpose of this particular solution to the problem, you can activate the hidden administrator account easily by using Command Prompt. Follow the instructions below in order to do this:

  1. Luckily for you, you don’t even need to be logged in to an account to access the Command Prompt.

  3. Instead or restarting, a blue screen will appear with several options. Choose Troubleshoot >> Advanced Options >> Command Prompt.

  1. Copy and paste the following command in Command Prompt and click Enter. You should be able to see the “The command completed successfully” message in no time.

net user administrator /active:yes

  1. Log into this admin account and wait for a couple of minutes before everything is ready.
  2. This will enable you to access your computer if your only account is locked out.
  3. After you are finished with the hidden administrator account, you can disable it again by opening an administrative command prompt and typing the following command:

net user administrator /active:no
