  1. Go to Search, type wsreset.exe.

Solution 3 – Reset the app’s Cache

If the Microsoft Store app’s cache accumulated over time, it’s a good idea to clear it. Maybe clearing the cache will also resolve this problem. Here’s how to clear the Store cache in Windows 10:

  1. Enable View Hidden Folders.
  2. Copy-paste this path in the Windows File Explorer address bar, but replace <username> with your account name:
    • C:Users<username>AppDataLocalPackagesMicrosoft.WindowsStore_8wekyb3d8bbweLocalState
  3. Rename the Cache folder from the LocalState folder. It’s your choice how to rename it.
  4. Create a new, empty folder and name it Cache.
  5. Restart your computer and you are good to go.

Copy-paste isn’t working on your Windows PC? Don’t let that ruin your day. Check out our dedicated guide and solve the issue in no time. Also, if you want to rename files like a pro, try one of these amazing tools.

Solution 4 – Check your Region settings

Microsoft Store doesn’t work the same way in every region. Also, if the region on your computer is different to your actual location, there might be some problems. So, we’re going to check if your region settings are set correctly. Here’s how to do that:

  1. Open the Settings app and go to Time & language section.
  2. Select Region & language tab and change your country or region.

You can also change your region by doing the following:

  1. Open Control Panel and select Region from the list.
  2. When the Region window opens go to Location tab and change the Home location. After you’re done click Apply and OK to save changes.
  3. Restart your computer and check if the issue is fixed.

You can’t open Control Panel? Take a look at this step-by-step guide to find a solution.


Solution 5 – Install Windows updates

As the Store is a part of Windows 10, frequent Windows updates may affect it. So, if this is a widespread problem, there’s a good chance Microsoft will eventually release a fixing patch.

To make sure you receive all the necessary patches, keep your Windows 10 up to date. Even though Windows installs updates automatically, you can always check by yourself by going to Settings > Windows Update.

Solution 6 – Create a new User Account

Some users also suggest that accessing the Store from an Account different than your default one can be helpful. So, if none of the previous solutions resolved the problem, try creating a new User Account and access the Store from it.

Here’s how to create a new User Account in Windows 10:

  1. Open the Settings app and navigate to Accounts.
  2. Now in the left pane go to Family & other people. In the right pane, click Add someone else to this PC.
  3. Select I don’t have this person’s sign-in information.
  4. Now click Add a user without a Microsoft account.
  5. Enter the desired username and click Next to proceed.

Windows won’t let you add a new user account? Follow some easy steps and create or add how many accounts you want!


Solution 7 – Re-register the Store app

And finally, if none of the previous solutions resolved the problem, you can go with re-registring the Store app package. Here’s how to do that:

  1. Right-click the Start Menu and open PowerShell (Admin).
  2. In the command line, copy-paste the following command and press Enter:
    • Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)AppXManifest.xml”}
  3. Restart your PC and try to log-in again.

Windows PowerShell doesn’t work? Fix the issue quickly with some simple solutions from this complete guide.


Solution 8 – Revert Windows Back to a Restore Point

If Store was working fine a few weeks or months back, then recently installed third-party software, especially anti-virus utilities, might be crashing the app in some way.

Reverting Windows back to system restore point will remove third-party programs installed after the restore point’s date and could feasibly fix Store. This is how you can restore Windows to a previous date with System Restore.

  1. Press the Win key + R hotkey to open Run.
  2. Enter ‘rstrui.exe’ in the Run text box, and press OK to open System Restore as below.
  3. Press the Next button, and select the Show more restore points option.
  4. Choose a date to restore Windows to. Select a restore point date when the Store app opened without any error message.
  5. Then you can click Next > Finish to restore Windows.

If you’re interested in more info on how to create a restore point and how would that help you, take a look at this simple article to find out everything you need to know.
