I need to create trusted pfx certificate which is trusted all windows users not only me.

I cannot find any instruction step by step how to get trusted certificate.

you have a few options here

• Self signing- the docs for that can be found here- https://docs.microsoft.com/en-us/windows/msix/package/create-certificate-package-signing
• There are third party certificate authorities where you can acquire a certificate
