Update applies to Windows 8.1, Windows RT 8.1, and Windows Server 2012
One of the most anticipated feature updates introduced with Windows 8.1 was the upgrade to Internet Explorer 11. The new browser was built with touch computing in mind and included several nifty upgrades, such as the ability to have 100 tabs open per window, side-by-side browsing, support for plugin-free HTML5 video, a Reading View, and more. Unfortunately, it also introduced some quirks, which Microsoft hopes to fix with a new patch.
There have been complaints over the browser crashing or running slow, websites not loading properly, and other unwanted (and unintended) behavior. Microsoft already listed some troubleshooting steps for specific issues, but if none of those do the trick, applying the patch might resolve any issue(s) you're facing.
The update is intended to improve the reliability of IE11 and applies to users of Windows 8.1, Windows RT 8.1, and Windows Server 2012 R2. If you're experiencing problems, give it a go and let us know how it works out.
