In the daily usage of Windows, we occasionally meet system or software errors/prompts like: "***.dll file is missing, xxx can't start...", causing us not to be able to run some software, especially a lot of games. In this case, the first thing we think of is often to search the error message and then download, install and register the corresponding missing DLL files, so as to achieve a manual repair. Therefore, this is not a troublesome thing for just a few missing DLL files, but too many, it will make a user feel hard to accept.
