Can you share Windows 10 image file?

[Windows Central Question]

Windows 10 will be out on July 29. Four of my computers at home are eligible, registered, and are waiting for the update. The upgrade file is 3GB they said. Is there a way for just one of my computers to download that file On July 29 and share it with the other three? I'm concerned about the data cap in our country.

in your case you might want to wait for the iso file to be made available.
