                            key.SetValue("Encoding", new byte[] { 0x80, 0x00, 0x00, 0x00 });
                        }
                    }
                }
                return true;
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
            return false;
        }

使用时:SetRegistery();注意使用时需要管理员运行
