Internet Explorer 10 (IE10) for Windows 7 was released two months ago. According to our benchmarks results, IE10 brings some performance improvements. Even if you're not an IE fan, there are plenty of 3rd party applications that relay on it and some [lamer] websites that won't work on any other browser but IE. Therefore, we recommend that you update.
For compatibility reasons, Microsoft designed IE10 to run in 32-bit mode by default - and unlike its predecessors - there isn't an obvious option or shortcut to launch the 64-bit version. It took us a while, but we finally found a way to run IE10 in 64-bit mode.
