Microsoft has released the Internet Explorer 11 for Windows 7. He will be installed automatically in the next weeks.
In this release, Microsoft has integrated or improved web techniques for better interaction and representation of websites. Web Designers will appreciate the automatic installation because developing websites for all the different versions of the IE is an unnecessary time consuming thingy.
The old fashioned and in 2014 out of support running operating system XP stays with the IE version 8.
