How can a Java application add itself to windows startup?

Question

Java

I tried different ways, for example through the registry:

String REG_ADD_CMD = "cmd /c reg add \"HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run\" /v \"AppName\" /d \"%PROGRAMFILES%\\AppPath\App.exe\" /t REG_SZ";
Runtime.getRuntime().exec(REG_ADD_CMD);

Works only under Windows XP. On Windows 8 it gives an access error.
Are there any working ways to add and remove yourself from autoload by clicking the button?
UPD: I'm posting a solution function, maybe it will be useful to someone

public void setStartup(boolean startup) {
    if (System.getProperty("os.name").toLowerCase().indexOf("mac") >= 0) {
      // автозапуск для Mac OS X
      String plist_text = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n";
      plist_text += "<!DOCTYPE plist PUBLIC \"-//Apple//DTD PLIST 1.0//EN\" \"http://www.apple.com/DTDsPropertyList-1.0.dtd\">\n";
      plist_text += "<plist version=\"1.0\">\n";
      plist_text += "	<dict>\n";
      plist_text += "		<key>Label</key>\n";
      plist_text += "		<string>ru.sp.MySquperApp</string>\n";
      plist_text += "		<key>ProgramArguments</key>\n";
      plist_text += "		<array>\n";
      plist_text += "			<string>/usr/bin/open</string>\n";
      plist_text += "			<string>/Applications/ChatMySquperApp</string>\n";
      plist_text += "		</array>\n";
      plist_text += "		<key>RunAtLoad</key>\n";
      plist_text += "		<true/>\n";
      plist_text += "	</dict>\n";
      plist_text += "</plist>";
      File plist = new File(System.getProperty("user.home")
          + "/Library/LaunchAgents/ru.sp.MySquperApp.plist");
      if (startup) {
        FileWriter writeFile = null;
        try {
          writeFile = new FileWriter(plist);
          writeFile.write(plist_text);
        } catch (IOException e) {
          log.fatal(e);
        } finally {
          if (writeFile != null) {
            try {
              writeFile.close();
            } catch (IOException e) {
              log.fatal(e);
            }
          }
        }
      } else {
        if (plist.exists()) {
          plist.delete();
        }
      }
    }else{
      // для виндовса
      String s = "";;
      if(startup){
        s = "cmd /C reg add HKCU\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run /v " +
                 "MySquperApp /t REG_SZ /d \"%PROGRAMFILES%\\MySquperApp\\MySquperApp.lnk\" /f";
      }else{
        s = "cmd /C reg delete HKCU\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run " +
                "/v MySquperApp /f\r\n";
      }
      try {
        Runtime.getRuntime().exec(s);
      } catch (IOException e) {
        log.fatal(e,e);
      }
    }
  }

On Windows 8, writing to "HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run\" needs privilege escalation, hence the error. Alternatively, write to "HKEY_CURRENT_USER\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run\", the application will automatically start only under the user under which it was written. Or elevate privileges to write to "HKEY_LOCAL_MACHINE" (application will run under all users).
