A piece of software is never perfect. And Windows 10 is not an exception. Some of the users often report an issue where their computers are stuck on a screen that says Preparing Security Options. When this is happening, these users will not be able to use their keyboard or mouse in any way and will be stuck on that screen until its processing is done. A similar issue was reported by users running Windows 7, Windows 8 or Windows 8.1. This issue often persists when the operating system is trying to load the lock screen or the log-on screen. And even sometimes when they are trying to load the Task Manager.
