reg-export:tldr:c9738

This command is used in the Windows command prompt or PowerShell to export a registry key and its subkeys, values, and data to a specified file.

Here's a breakdown of the command syntax:

• reg export: This is the command to export the registry key.
• ${key_name}: This is a placeholder for the name or path of the specific registry key that you want to export. You need to replace ${key_name} with the actual name or path of the key.
• ${path\to\file-reg}: This is a placeholder for the destination file path where you want to export the registry key. You need to replace ${path\to\file-reg} with the actual file path and filename that you want to use for the exported registry key.

For example, if you want to export the registry key "HKEY_LOCAL_MACHINE\SOFTWARE\Example" to a file named "example.reg" located in the "C:\Exports" directory, the command would be:

reg export HKEY_LOCAL_MACHINE\SOFTWARE\Example C:\Exports\example.reg

After running this command, the specified registry key and its contents will be exported to the "example.reg" file.
