How to Fix Microsoft Store Error Code 0x80073CFF in Windows 11
If you’ve encountered the dreaded Microsoft Store error code 0x80073CFF, you might be frustrated, as this issue prevents you from downloading and installing apps. This error typically pops up with a message indicating that your system needs to be sideloading-enabled. Fortunately, the underlying causes of this error can range from corrupted Store files and outdated system components to group policies that may be misconfigured. This guide walks you through several effective solutions to fix this issue and restore your Microsoft Store functionality.
Step 1: Enable Sideloading
The first step in addressing this error is to enable sideloading on your Windows 11 system, which allows you to install apps from sources outside of the Microsoft Store. Follow these instructions:
- Right-click on the Start menu and select Settings.
- In the Settings menu, navigate to Update & Security, and then click on For developers. Alternatively, on Windows 11, go to System and then For developers.
- Locate the option for Sideloading apps and toggle it to
On. On Windows 11, simply enabling Developer mode is sufficient. - If prompted by any confirmation messages, proceed to confirm.
- For the changes to take effect, restart your computer and then check the Microsoft Store again to see if the issue has been resolved.
Step 2: Reset Microsoft Store Cache
If enabling sideloading doesn’t resolve the issue, resetting the Microsoft Store cache might do the trick. This step is essential as it clears any corrupted files that may disrupt the Store’s functionality. Here’s how to reset the cache:
- Open the Windows search bar and type
wsreset.exe, then press Enter. - A black command window will appear. You don’t need to close this window; just wait for it to finish.
- Once the window disappears, the Microsoft Store will automatically restart.
- Try accessing the Store again to check if the problem persists.
Step 3: Check for Corrupted System Files
Another common reason for this error could be corrupted system files. Running the System File Checker (SFC) can help identify and repair any corrupted files. Here’s how to do this:
- In the Windows search box, type
cmd. - Right-click on Command Prompt and select Run as administrator.
- When prompted by User Account Control, click Yes to allow changes.
- In the Command Prompt window, type or paste the command
sfc /scannowand hit Enter. - Allow the scan to complete. This may take some time.
- Once the scan finishes, restart your computer and then check the Microsoft Store functionality.
Extra Tips & Common Issues
While following the steps above, keep in mind these extra tips to enhance your experience:
- Ensure your Windows 11 operating system is up to date by checking for updates in the Settings under Windows Update.
- If the issues persist, consider running the Windows Store Apps troubleshooter. You can find this in Settings under Update & Security, followed by Troubleshoot.
- Frequent app crashes or download failures might also indicate issues with your internet connection. Check that your network is stable.
