IE 11 on Windows 7 VS IE 11 on Windows 10

Question

Could anyone please detail the difference between IE 11 on windows 7 and IE 11 on windows 10.

My organization has done lot of testing while moving from IE 8 to IE 11 on windows 7 and now they want to upgrade to windows 10.

However before moving to Win 10, they want to be sure that IE11 on Win 10 is exactly same as IE 11 on Windows 7.

I am not able to find any article on Microsoft website, which explains it.

Thanks in Advance.

Regards

Answer 1

I would imagine they render the page in the same way (CSS etc.) but there are some security changes.

On Windows 8 and later IE can run in a AppContainer sandbox. Enhanced Protected Mode can cause issues with 3rd-party browser extensions and local files. EPM is optional and can be turned on/off.

There are also changes at the network level and backend storage.

If you rely on 3rd-party extensions or local file/localhost access you might want to do some testing before migrating, if not then I don't see any real showstoppers.

Answer 2

I noticed another change. IE in Windows 10 supports Math.sign and other operations. Windows 7's doesn't.
