There does not appear to be a "README.txt" file for Windows installation in either the main SageMath repository or the website repository. If such a file ever existed, it's long gone. I even checked at archive.org for a backup copy, but since the robots.txt file has been blocking the /mirror/ directory since 2009 they don't have one either.
The simplest solution is to delete the link from the documentation, unless someone wants to create the file.
