 | OSS                            | 支持     | 极简化更新，是一套独立的更新机制。只需要在文件服务器中放置version.json的版本配置文件。组件会根据配置文件中的版本信息进行更新下载。(支持Windows，MAUI Android) |
 | 回滚                           | 待测试   | 逐版本更新时会备份每个版本，如果更新失败则逐版本回滚。       |
 | 驱动更新                       | 待测试   | 逐版本更新时会备份每个版本的驱动文件（.inf），如果更新失败则逐版本回滚。 |
-| 系统服务                       | 待测试   | 开机时和升级时会检查升级是否成功，如果失败则根据遗言还原之前的备份。遗言是更新之前就已经自动创建在C:\generalupdate_willmessages目录下的will_message.json文件。will_message.json的内容是持久化回滚备份的文件目录相关信息。（需要部署GeneralUpdate.SystemService系统服务） |
