Unfortunately, according the release notes, Internet Explorer supports Windows 10 version 7 and higher only. It means Internet Explorer 10 can not be installed on Windows Vista or Windows XP.
The Internet Explorer Platform Preview requires Windows 7 (x86 or x64) Operating System. Platform Preview 4 and later require updates to be installed on Windows 7 systems, after which your computer will require a restart.
This is bad since there are many people who use Windows XP as the operating system on their computers. In addition, other browsers such as Chrome, Firefox, Opera, and Safari still support Windows XP on their last version. There are many reason why users do not want to upgrade their Windows operating system to the last windows version. For example software price or minimum computer specs. This situation will make Internet Explorer is difficult to grow up in market. But we will know later.
