By default, most versions of Windows record an event every time a user tries to log on, whether that log on is successful or not. You can view this information by diving into the Event Viewer, but there’s also a way to add information about previous logons right on the sign in screen where you can’t miss it. To make it work, you’re going to have to dive into the Windows Registry or, if you have a Pro or Enterprise version of Windows, the Group Policy Editor. But don’t worry. The changes are pretty simple and we’ll walk you through them.
