1. Copy the above contents to Notepad.
2. Save the file with .reg extension — e.g., audioendpoint_service.reg
3. Double-click the registry file to apply the settings to the registry. Click Yes when prompted for confirmation.
4. Open the C:\Windows\System32 folder and verify if the file AudioEndpointBuilder.dll exists. If it doesn’t, you may need to run DISM and SFC to restore the file. AudioEndpointBuilder.dll is the DLL for the Windows Audio Endpoint Builder service.
5. Restart Windows for the changes to take effect.

The audio functionality should have been restored now!

之後就應該可以解決 Windows Audio 這個服務沒辦法啟動的問題
