Here’s a short, interesting story-like dive into — a browser that arrived like a paradox, loved by developers but ignored by the world. In the spring of 2011, the web was a battlefield. Firefox was gaining ground, Chrome was sprinting ahead, and Internet Explorer — still bruised from the IE6 debacle — was trying to stage a comeback.
When she finally decommissioned it in 2022, she whispered: “Goodnight, you weird, unsung 32-bit hero.”
The weapon? .
Now, the oddest detail: the user agent string. If you were on 32-bit IE9, it reported: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0) No “Win64” flag. On 64-bit IE9, it added Win64; x64 . So websites saw the 32-bit version as the “normal” one. Developers often tested only that, and 64-bit IE9 became a ghost.

One rainy night, a system admin named Clara noticed something strange. Her company’s internal CRM, built on ancient ASP and ActiveX, would only run in IE9 32-bit — not 64-bit, not IE10, not Edge. It needed a specific DLL registered in SysWOW64 , not System32 . The 32-bit version of IE9 was the only portal to that legacy world.
