推荐答案

您需要提升的特权才能做到这一点.如果在运行脚本"操作中执行此操作，请将其操作提升类型"属性设置为提升到最大可用特权".要成功生效，必须成功执行请求特权"操作.

You need elevated privileges to do that. If you do this in a "Run script" action, set its "Action elevation type" property to "Elevate to maximum available privileges". A "Request privileges" action must have been executed successfully for that to have an effect.

要在任何脚本中执行此操作，请像这样包装您的代码:

To do this in any script wrap your code like this:

context.runElevated(new RemoteCallable() {
    public Serializable execute() {
        // run registry code here
        return null;
    }
}, true);
