Fix Microsoft Store Error 0x80073D26

You are trying to download an app and the Microsoft Store just stops mid-install with error 0x80073D26, leaving you stuck in a loop. This happens when the local Store cache is corrupted and needs to be flushed or re-initialized.

Why this happens

The Store cache has become corrupted or out of sync with your account permissions. This prevents the installer from reaching the final stage of the setup.

What you will need

You will need administrative access to your computer to run the repair commands.

Steps

1. 01
   Press the Windows key + R on your keyboard to open the Run dialog.
2. 02
   Type wsreset.exe and hit Enter.
3. 03
   Wait for the black command window to close automatically and for the Microsoft Store to relaunch on its own.
4. 04
   Attempt the app install again; if it still fails, right-click the Start button and select Terminal (Admin) or PowerShell (Admin).
5. 05
   Paste the following command into the terminal and press Enter: Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)/AppXManifest.xml"}
6. 06
   Ignore any red text that scrolls by during the process, wait for it to finish, and try your install again.
7. 07
   If the issue persists, run sfc /scannow in the same admin terminal to repair corrupted system files.
