How to Verify GPG signature of Trisquel on Windows10

Hello,

I have downloaded the trisquel_7.0_amd64.iso from the trisquel.info web-site on a desktop with Windows10.

How can I verify the GPG signature using the gpg4win / Kleopatra. If not, are there any other tools to verify the GPG signature on Windows10.

Thanks.
