Method 1: Run the Windows Store Troubleshooter.

Troubleshooting Microsoft Store may help to fix 0x80040154 error

Troubleshooting Microsoft Store is the best way to resolve any issues that arise when you open it or download apps from it. The entire procedure is very simple and easy. Here’s how to troubleshoot the Error Code 0x80040154 on your computer –

If it does not resolve the problem, you will be given a set of instructions to follow in order to resolve it.

Method 2: Reset the Windows Store Cache

Use the wsreset.exe command

If troubleshooting fails, the Error 0x80040154 could be caused by a cached file within the Store app. Microsoft’s wsreset tool is a useful tool for restoring Windows Store to its default state. Run this command-line program and see if it helps you solve your problem.

  1. Launch Command Prompt with administrator privileges.
  2. Enter “wsreset.exe” (no quotes) into the search box.

Note: This code will be executed next and will clear all cache associated with your Microsoft Store.

  1. Close all open windows and restart your computer.
  2. Sign back into your PC and see if it helped to resolve the root cause.

Method 3: Clear the Contents of the DataStore Folder

Clear the Contents of the DataStore Folder

On Windows 10/11, the DataStore folder stores temporary and log files related to current and past system updates.

Stop the Windows Update service by opening Windows Services Manager. Then, proceed as follows:

  1. Using the Win+E hotkey, launch File Explorer.
  2. In the address bar, paste the following command:


  1. To open the DataStore folder, press Enter.
  2. Select all of the files and folders in the DataStore folder.
  3. Delete all of them.
  4. Now, using Windows Services Manager, restart the Windows Update service and check if the problem has gone away.

Method 4: Repair the Microsoft Store App

If you are still unable to install or update apps from the Microsoft Store, the issue could be with the Store app itself. Microsoft does not provide a way to uninstall its store app by default. However, you can do so legally using Windows PowerShell. Here’s how to complete this task –

  1. To access the Power Menu, press Winkey + X. Next, select Windows PowerShell (Admin).
  2. When the UAC prompts you, click Yes to allow PowerShell to run as administrator.
  3. Copy/paste the following codes and run them separately –
  • Get-AppxPackage *windowsstore* | Remove-AppxPackage
  • Get-AppXPackage *WindowsStore* -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}

That’s all there is to it; the Windows Store App has been reset to its default settings.

  • net start bits
  • net start msiserver
  1. Once the services are restored, try updating your system again to see if the problem persists.
