Java之修改注册表

Runtime类可以用来执行cmd命令，既然可以执行cmd命令，当然就能通过cmd命令修改注册表了。

Map map = new HashMap();
map.put("DisplayName", "TestValue");//注册表的属性名和属性值
map.put("DisplayVersion", "xxx");
// map.put("NameXXX", "ValueXXX");
String commandPrefix = "cmd.exe /k reg add ";
String key = "\"HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\{EDB3BE72-EED9-4006-B848-9287A18E0F86}_is1\"";// 注册表的key
// String key = "\"HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\XXX...\"";
// String key = "\"XXX\\XXX\\XXX\\XXX...\"";
for (String k : map.keySet()) {
	Runtime.getRuntime().exec(commandPrefix + key + " /v " + k + " /d " + map.get(k) + " /f");
}
