IE 10 was originally designed to run in Windows 8 and now it has been tested and could be stable to run in Windows 7.
IE 10 is claimed to be at least 20% faster than IE 9.It could also support 60% more web standards than IE 9(CSS 3 transformation,animations,gradients etc).It enhances the security features such as Do Not Track enabled by default.Of course,the test result will be better than IE 9.
Microsoft will put into auto updates in the coming weeks.That means if you’re running genuine Windows 7 and enabling Windows Update,you will get it soon to replace IE 9,getting better web surfing experience(if you’re still IE fans).
If you don’t want to wait,you could download from windows.microsoft.com/ie and install it by your own.It could be fairly simple.
