To download the ISO legitimately, the user must visit the Microsoft Software Download site. Historically, Microsoft provided a direct download interface where users could select their edition (Standard, Pro, or Enterprise) and language. To bypass the web-based download manager and get a direct ISO link, tech-savvy users often had to spoof their browser’s user agent string to mimic a non-Windows device (such as a mobile phone or Linux machine). This trick forces the website to offer a direct ISO download link rather than an executable installer.
