Open the program to be downloaded with the EDGE browser of Win 10 and download it again. After completion, it still shows that the program signature is damaged or invalid, but the advantage of this is that we can find out where the downloaded file is and click "Open Folder" in the upper right corner.

Click to open the folder where the downloader is located.

After opening the folder, we tried to double-click the downloaded program and run it. At this point, the system prompts "This program may cause security risks to the computer". As long as students know the credibility of the download program, they don't have to pay attention to this prompt and click "More Information" directly.

After clicking, the system will remind you again that Windows 10 is also very detailed, and the security consultation is in place. Now you can see the name of the program and the information of the publisher. If the open program is shown as "Unknown Publisher" as shown in the figure below, there are two possibilities. One is that the publisher is not filled in the application at all, and the other is that the system failed to read the publisher information due to the network speed. Here we insist on clicking "Run". After clicking, the program finally started running.
