To reopen a service that was stopped via msconfig.exe, you can follow these steps:

- Restart your computer to apply the changes.
2. Use Service Manager:

- In the Services window, locate the service you wish to re-enable.
- Right-click on the service name and select “Properties”.
- Set the “Startup Type” to “Automatic” or “Manual” and click the “Start” button.
