Set (default) zoom level of IE11 programatically (i.e. via regedit)

Question

Before running any web tests I want to ensure that the IE11 is on zoom level 100%.

Is there any way to programmatically reset the zoom level to 100%? I'm using C# and would prefer an official Microsoft API, if there is none, I guess I need to set some registry or configuration setting.

Note: I'm not looking for a solution for resetting the zoom level using JavaScript or HTML!

what about [SendKeys](http://stackoverflow.com/q/15292175/2596334)? `alt-v, z, 0` — Scott Solmer, Oct 21 '14 at 14:02
Don't know if that's a good solution, however, unfortunately not possible at all: my web testing framework already throws an exception on IE-start if the zoom-level is not 100%. So no time for me to do any SendKeys-stuff. — D.R., Oct 21 '14 at 14:08

Well then would not the right thing be to detect that the zoom level isn't 100% and then reset it - rather than letting the application crash because it assumes the zoom is 100%?

Close the browser with zoom setting as 100%

Go to RegEdit

HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Zoom
Change ResetZoomOnStartup2 value to 0 (It doesn't default the zoom setting to the regular one)

OR

In windows 10, go to display settings and change the scaling to 100%

That should set the basic zoom to 100% in IE

You can use the following code:

 string registryKey = @"Software\Microsoft\Internet Explorer\Zoom";
 var regKey = Microsoft.Win32.Registry.CurrentUser.OpenSubKey(registryKey, true);
 if (regKey != null)
 {
     regKey.SetValue("ZoomFactor", unchecked((int)0x00100000), RegistryValueKind.DWord);
 }

Set (default) zoom level of IE11 programatically (i.e. via regedit)
