Challenges with IE browser in Selenium Webdriver:

Issue 1: openqa.selenium.NoSuchWindowException
This is a common issue with Selenium and you can avoid this by doing some IE setting, which we are going to discuss now.

Issue 2: sendKeys works very slow it takes 1-2 second to type each character.
This is a known issue with Selenium and it only happens once you work with IE 64 bit driver.

Solution- You can download IE Driver 32 bit and start using it, even you are working with 64 bit OS this 32 bit IE driver works every time

Issue 3: Unexpected error launching Internet Explorer.
Protected Mode must be set to the same value. When I started working with IE this was the first exception, which I used to get, and I was sure that this related to some browser setting.
You can make the below changes in IE and this exception will not come again.

Issue 4: Unexpected error launching Internet Explorer. 
Browser zoom level was set to 0% By the name itself, you can see that we have to set the zoom level to 100 % to make it work.
You can follow below instruction to set browser zoom level.
