Hello, @Rajesh sharma! Welcome to the Zoom Community! It’s great to have you here.
I understand that you’d like to restore Zoom to its default settings. Currently, the Zoom Workplace app does not include a single “Reset all settings to default” option.
If you’d like to return Zoom to a clean/default state, the best workaround is to:
Sign out of the Zoom desktop app
Uninstall the Zoom desktop app
Reinstall the latest Zoom Workplace desktop app
Sign back in and review your settings again
Note: Zoom provides separate reset or restore options for specific parts of the app. Each section of the app includes its own reset or restore settings. You can learn more by visiting the article 'Changing settings in the Zoom Workplace desktop and mobile app.'
