Running ie10, ie11 at same time for testing?

Question

I recently installed ie11 on my Windows7 machine and do browser testing for all versions of ie on it in the document. I also do tests on Browserstack. I have client now that INSISTS I test on ie10 directly.

As you know, Windows won't let you run multiple version if ie, un-install ie directly, or reinstall an older version when a newer version is already installed. I don't want to have to uninstall/reinstall ie11, reinstall/install ie10.

Is there a work around where I can run both version without have to uninstall one or the other?

Answer 1

On modern.ie you can find free virtual machines for every version of Internet Explorer.

Answer 2

Press F12 and you can go backward to previous versions of IE (click on browser mode). First go to the website and then change browser mode (the opposite order won't work)
