The most confirmed cause is a leftover or active Xbox Companion App, which breaks dependencies needed by newer versions of Xbox or Store apps. Other known triggers include corrupted cache, registry inconsistencies, or problems during a recent Windows update.
1. Clear Microsoft Store Cache Files
Cache files are temporary files stored by Windows. Sometimes, the Microsoft Store cache can become corrupted due to reasons like power failures or sudden shutdowns. There is a strong possibility you are seeing the 0x80073CFB error because of corrupted Microsoft Store cache files.
2. Reset or Repair Microsoft Store
You can also use the Reset and Repair options available for Microsoft Store. We recommend trying the repair option first. If that doesn’t solve the error, use the reset option.
3. Run Windows Apps Troubleshooter
The Windows Apps Troubleshooter is a tool that helps identify and fix problems with Microsoft Store apps.
4. Disable Proxy Server
A proxy server acts as an intermediary between your computer and the internet, and if enabled, it can sometimes prevent downloads or access to websites.
5. Run System File Checker
System File Checker is a tool developed by Microsoft for Windows. It scans all system files and replaces corrupted files with a cached copy.
6. Clear Software Distribution Folder
The Software Distribution folder is found in the Windows directory and stores files needed for Windows Updates. Clearing this folder can sometimes resolve the 0x80073CFB error.
7. Reinstall Microsoft Store
Reinstalling the Microsoft Store can also fix the 0x80073CFB error. This requires using PowerShell, as the Microsoft Store can’t be reinstalled from the Control Panel or Settings.
