Answer 1

You could use System.exec to launch regedit yourfile.reg

Here is how to do it :

String[] cmd = {"regedit", "yourfile.reg"};
Process p = Runtime.exec(cmd);
p.waitFor();

Last line is optional, it only allows you to wait until the operation is over.

Answer 2

If you're already on Java 1.6, just grab java.awt.Desktop :

Desktop.getDesktop().open(new File("c:/yourfile.reg"));

It will launch the file using the default application associated with it, as if you're doubleclicking the particular file in Windows explorer.

Answer 3

This can achieved through Process Builder in JAVA. Please consider the following example for this:

ProcessBuilder processBuilder = new ProcessBuilder("regedit", "reg_file_to_run.reg");
Process processToExecute = processBuilder.start();

And then you can optionally wait for the completion of process execution with this line:

processToExecute.waitFor();

Note: If command in your registry file asks for confirmation prompts while making changes in registry entries, you can perform it silently as well with '/s' option. Like this:

ProcessBuilder processBuilder = new ProcessBuilder("regedit", "/s", "reg_file_to_run.reg");

With this command would be executed silently without any confirmation prompt.
