| **Troubleshooting**           | While functioning, Parallels Desktop automatically creates a log file that can be used by the Parallels support team for solving problems and improving the product. If you select the **Use detailed log messages** option, Parallels Desktop will start creating a more detailed log file. It can be helpful for the Parallels support team, but uses more hard disk space and may lower the system performance. You're not recommended to enable this option until you're asked to do so by the Parallels support team. |
| **Reset all dialog warnings** | Some Parallels Desktop dialogs and windows are provided with the **Do not show this message again** option. If you select this option, the corresponding dialog will not appear the next time you perform the same operation. Using the **Reset Warnings** button, you can reset all dialogs and windows with this option selected to display them again each time you initiate the corresponding operation.                                                                                                               |
