Hi,

I think Microsoft provide this features to support to debug, test and speed up your webpage on the fly and without any need need of any third party application.

If we you want to hide the developer tool you can simply press F12 again or on the 'x' sigh at the top right.

Hi Varun,

You cannot really disable the F12 on the client side.
What you can do is capture the key press event and handle that event when F12 was the pressed key (you could also check which browser type it is using Javascript [you specifically specified IE]), but it can easily be bypassed by clever users, so it's not a strong solution.

Another approach - You could (to some extent) "hide" your real Javascript by using Obfuscation [^]

Best,
H
