FIX: Windows has blocked this software because it can’t verify the publisher

Error “Windows has blocked this software because it can’t verify the publisher” comes up when your security settings cannot verify the publisher of the content. Even though, i do not like Explorer because it does this un-necessarily but as i understand you and many of my clients like Internet Explorer and are used to it. Internet Explorer has been replaced with Edge in Windows 10. Since the earlier versions of Windows (before 10) were heavily dependent on Internet Explorer for most-functions, any corruption on it causes affects other areas of the system. I will walk you  through the steps in this guide to address the issue; but if and when you make up your mind about changing browsers, switch to “Google Chrome” – it is fast,  reliable and secure with most features built-in to it unlike Internet Explorer; which is linked to allow other programs to change its features.

Steps to Fix Windows has blocked this software because it can’t verify the publisher

Open Internet Explorer and Press the Alt key while you’re on Internet Explorer for the menu to appear (on the top) and then choose Tools. From Tools choose Internet Options and then Click the Security Tab – Custom Level button.
