Many corporations and government institutions rely on intranet sites and internal tools built specifically for IE 6 or 7. These applications often utilize ActiveX controls, VBScript, or proprietary CSS rendering that simply break in modern standards-compliant browsers. A portable version allows an IT technician to support these systems without infecting their main workstation with an outdated browser.
The illusion shatters the moment you type a URL. I tried github.com. The page loaded as a vertical tower of broken CSS—Times New Roman text stacked on top of each other like a ransom note. I tried youtube.com. IE6 offered to install Flash Player 7. I declined.
The modern web runs on HTTPS, Flexbox, Grid, WebGL, and a dozen JavaScript frameworks that IE6 has never met. The portable version doesn't even support TLS 1.2. That means 99% of the internet throws a "Cannot find server or DNS error." internet explorer portable old version
But that’s the point. You aren't supposed to browse today with IE6. You are supposed to browse yesterday.
The era of Internet Explorer as a mainstream browser is long dead. But as a portable relic, it remains a necessary ghost in the machine—a ghost that, if handled with care, will keep your legacy empire running for another decade. Further Reading & Resources:

While not strictly "portable," Microsoft once provided free, time-bombed Windows VMs (IE6, IE7, IE8, IE9, IE10, IE11) for cross-browser testing. These VMs run in VirtualBox or VMware Player. They are better than portable versions because they provide the complete, authentic environment. Search: "Microsoft Edge Developer VMs for IE testing" (note: Microsoft discontinued them, but Archive.org hosts mirrors).
There is a cultural interest in experiencing the internet as it existed in the late 90s and early 2000s. Enthusiasts use portable versions of IE 5 or 6 to browse archived versions of websites (via the Wayback Machine) to experience the authentic "Web 1.0" aesthetic.
Using an old IE on a modern network exposes your machine to drive-by downloads. Even visiting a compromised legacy intranet site could drop ransomware because IE’s sandbox is trivial to escape.
