### Feedback

To participate in the Customer Experience Application, select the corresponding option. If you join this application, Parallels will collect information about your Mac and virtual machines configuration. The collected information will help us to make the product better fit your needs.

If you join, only the following types of data will be collected:

* hardware configuration of your Mac
* software configuration of your Mac and virtual machines (the names and versions of the operating systems and software installed in them)
* configuration files of virtual machines

Any types of private information like your name, e-mail, address, phone number, and keyboard input will not be collected.

For more details, visit the Customer Experience Application page at the Parallels website (follow the link in the pane).

### Troubleshooting

While running, 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 slightly lower the system performance.

### Resetting Hidden Messages

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 next time you perform the same operation. Using the **Reset Warnings** button, you can reset all dialogs and windows with this option selected so that they would be displayed again each time you initiate the corresponding operation.

### Locking Parallels Desktop Preferences

If you want to prevent Parallels Desktop Preferences from further unauthorized changes, click the Lock icon at the bottom of the window. The next time anybody wants to change the settings in any pane of Parallels Desktop Preferences, an administrator's password will be required.

**Note**: Locking Parallels Desktop Preferences is not supported in the App Store edition of Parallels Desktop. For more information on the differences between the Standard and App Store editions, follow this [link](https://kb.parallels.com/123796).
