This post tells you how to fix Microsoft Store 0x800706D9 in Windows 10/11.

Fix: Error 0x800706D9 when Updating Store Apps

To resolve Microsoft Store Error 0x800706D9 in Windows 10, follow these steps:

  1. Launch the Services MMC by running services.msc from the Run dialog.
  2. Double-click Storage Service and set it to Automatic (Delayed Start)
  3. Click Start to start the services manually.
  4. Also, make sure that the following services are started/running:
    • Windows Defender Firewall (previously “Windows Firewall”)
    • Windows Update
    (If you’re using a 3rd party firewall application, Windows Defender Firewall will be disabled automatically. That’s normal. You don’t have to start the firewall service in that case.)
  5. Exit the Services console.

You should be able to download or update Store apps now.

Note: If Windows Firewall doesn’t start correctly, check out the article Windows Firewall Error 0x6d9 “The snap-in failed to load” for a fix.

Note: Storage Service provides enabling services for storage settings and external storage expansion. If this service is not running, drives may go missing in the Storage Settings and App Save Locations dropdown. The Storage Service may be the main interface with which the Windows Store apps (UWP) can write to the file system. The classic (Win32) desktop apps may not need this service anyway.

Reinstall Windows Store

If starting the Storage service doesn’t help, you may try reinstalling the Windows Store using PowerShell, using the following command-line from an admin PowerShell window:

Get-AppxPackage -allusers Microsoft.WindowsStore | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
reinstall windows store using powershell
Restore Windows Store using Add-AppXPackage command

  2. This worked perfectly. Just like the prior comment, i’ve been looking for days on google and YouTube. This is the only one that worked, and it was very simple. Thank you so much, great job.


  3. That is just it, the store works fine. I can update and install apps, except OneNote. So it is not the store. How do I fix it, if it is just one app that wont install.

  4. Super solution Merci! J’ai simplement activé le “Service de stockage” et le Microsoft Store fonctionne à nouveau! Je me demande quand même de quelle manière il a pu se désactiver tout seul…

  5. This was very helpful! I was stuck on this problem for 3 days then I just quit, but I decided to try to troubleshoot it again after 1 week or so and this really helped

  6. Worked perfectly! Thank you so much. I’ve been trying to install updates all morning and kept getting a message that said, “Something happened on our end”. Tried the update troubleshooter and all kinds of other “remedies” that didn’t help. This fixed it!
