When downloading or updating your apps from the Windows Store, you might encounter error code 0xc03f40c8. Here are some steps to fix the problem.

1: Microsoft Store Error 0xc03f40c8 - Windows Repair

Windows Repair can reset all the Windows Update settings saving you a lot of work.

Download Windows Repair from MajorGeeks.

Boot into Safe Mode.

Click on Jump to Repairs.

Uncheck All Repairs.

Check 27.02 to reset the Store completely and click on Start Repairs.



2: Microsoft Store Error 0xc03f40c8 - Run Troubleshooter

The Windows Store App Troubleshooter should fix the error as a known issue.

Click Start > Settings > Update & security > Troubleshoot.

Scroll down on the right and click on Windows Store Apps.



Click on Run the troubleshooter.

Wait while the troubleshooter looks for known problems.



If any problems were discovered, they are almost always fixed automatically.

3: Microsoft Store Error 0xc03f40c8 - Reset Store

Click Start > Settings > Apps & features. Find, and click on Microsoft Store on the left. Click on Advanced options.

Scroll down and click on Reset.



4: Microsoft Store Error 0xc03f40c8 - Re-Register Store

Open Powershell and type in:

PowerShell -ExecutionPolicy Unrestricted -Command “& {$manifest = (Get-AppxPackage Microsoft.WindowsStore).InstallLocation + 'AppxManifest.xml' ; Add-AppxPackage -DisableDevelopmentMode -Register $manifest}”

Press enter and reboot.

5: Microsoft Store Error 0xc03f40c8 - Clear Store Cache Manually



Press the Windows key + X and choose Windows PowerShell (Admin). Right click on that and Run as administrator.

Type in wsreset.exe. and press enter.

Be patient and wait until you see the flashing cursor again, so you know that the cache has been cleared.



6: Microsoft Store Error 0x8004e108 - Internet Connection or Time

While less likely, people reported two other problems that we assumed you already checked, so we'll cover them both as a last possible step.
