Hi Satish 2561.
Internet Explorer 11 is the only version of IE that will work on Windows 10: you can't downgrade IE or install another IE version.
If you are having problems with viewing a website, try compatibility view: you can read more about this IE feature at
http://windows.microsoft.com/en-gb/internet-explorer/use-compatibility-view#ie=ie-11.
You can emulate IE10 using IE11 by pressing F12 (Developer Tools) then selecting
Emulation and the IE version you want to emulate. Remember that this setting is not persistent: it will only emulate while Developer Tools remains open.
Bye.
