### Right-click context menu is missing on Windows 11
Assuming you've already restarted `explorer.exe` via the right-click context menu in Task Manager (or have rebooted Windows), this is happening sometimes on Windows 11 for reasons which I still trying to find out.
What might help in those cases and when the classic context menu is preferred, is to manually register the shell extension from a command prompt **with admin rights** :
```plaintext
cd
regsvr32 Mp3tagShell.dll
```
