Therefore, whenever you download a file directly from an official source, you can verify the authenticity of the file. So how do we check the digital signature in the windows1 system? Now I will explain to you the method of checking the digital signature in the windows1 system.

1. Through the file explorer

1) First, open the Windows file explorer and navigate to the location where your program is saved;

2) Right-click the installation file and click Properties;

Microsoft released a WindowsSDK program called SignTool. WindowsSDK or software development kit does not come with Windows built-in. It is suitable for developers, who should install it separately. If you are interested in trying this method, please make sure that you have the SDK that suits you.
