I believe that most Public Libraries are now running Windows 10, & you should be able to extract the contents of the zip to a flash drive.
Your local library should have a website that you can see it if it is open. All the public libraries around where I live are open, COVID restrictions applicable though. Call your library ask for the person that works with the public access computers and ask questions. Can I download, can I unzip a compressed folder, can I copy contents to a flash drive, etc.
You don't have a friend, classmate, etc. with a windows computer that lives near you?
