How to Fix Windows Error 0x80073D02

What Causes This?

Windows error 0x80073D02 usually appears when Microsoft Store is trying to install, update, or move an app that is still running in the background. In many cases, the app itself, a related process, or the Microsoft Store cache is preventing Windows from completing the change. It can also happen if temporary files, a stuck Store service, or a pending restart is interfering with app deployment.

Common Symptoms

• Microsoft Store app updates fail with error 0x80073D02
• You cannot install or move an app to another drive
• Store downloads get stuck on Pending or Starting download
• An app appears closed, but Windows says it is still in use
• Microsoft Store opens, but installs repeatedly fail

How to Fix It Manually

1. Close the app that is causing the error

   • If the Store shows which app failed, open that app and close it normally.
   • Also close any related windows, background launchers, or system tray icons tied to that app.
   • Try the install or update again in Microsoft Store.

2. End background app processes in Task Manager

   • Open Task Manager with Ctrl + Shift + Esc.
   • Click More details if you only see the simple view.
   • Under the Processes tab, look for the app that failed to update, plus related items like Microsoft Store, Gaming Services, Xbox, or other app helper processes.
   • Select each one and click End task.
   • Reopen Microsoft Store and try again.

3. Restart your PC

   • Click Start > Power > Restart.
   • After Windows restarts, do not reopen the problem app before testing the Store update.
   • Open Microsoft Store > Library and click Get updates.

4. Clear the Microsoft Store cache

   • Press Windows + R to open Run.
   • Type wsreset.exe and press Enter.
   • A blank Command Prompt window may appear for a moment, then Microsoft Store should reopen automatically.
   • Once it finishes, try installing or updating the app again.

5. Repair or reset Microsoft Store

   • Open Settings with Windows + I.
   • Go to Apps > Installed apps.
   • Find Microsoft Store, click the three dots, then choose Advanced options.
   • First click Repair.
   • If that does not help, return to the same screen and click Reset.
   • Open Microsoft Store again and test the install.

6. Check for Windows updates

   • Open Settings > Windows Update.
   • Click Check for updates.
   • Install any available updates, especially Store, app platform, or servicing updates.
   • Restart your PC if prompted, then try again.

7. Re-register Microsoft Store with PowerShell

   • Right-click Start and choose Terminal (Admin) or Windows PowerShell (Admin).
   • Copy and paste this command, then press Enter:

   Get-AppxPackage -allusers Microsoft.WindowsStore | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

   • Wait for it to finish, restart your PC, and test Microsoft Store again.
