Internet Explorer 9 (32 Bits) Direct

: The 32-bit version featured the new "Chakra" JavaScript engine. It utilized a background thread for Just-In-Time (JIT) compilation , allowing users to interact with pages while the browser generated faster code in the background.

: Interestingly, the 64-bit version of IE9 lacked this JIT compiler, making it up to four times slower than its 32-bit counterpart in JavaScript benchmarks.

: Users could drag a website favicon to the Windows taskbar to "pin" it, allowing the site to function more like a standalone desktop application.

: IE9 was compatible with Windows 7, Windows Vista SP2 , and their server counterparts. Notably, it was the first version of IE to not support Windows XP.

While IE9 was available in both 32-bit and 64-bit editions, the 32-bit version was the default and generally recommended choice due to its superior performance at the time.

: A long-awaited feature that included a security-enabled manager with the ability to pause and resume transfers.
