How to Know Who Logged into Windows 10?

How to Know if Someone Logged Into Your Windows 10?

Windows 10 lets you see which users are logged into your PC using Event Viewer (and when they logged in). This article is dedicated to Windows Home Edition users interested in Windows auditing.

event viewer

Event viewer is a Windows component that enables administrators and regular users to view event logs on a local or remote machine. It uses event IDs to define uniquely identifiable events that a Windows computer might encounter.

Event Viewer displays a log of application and system information messages, including warnings and errors (these are displayed even if your system is running correctly).

This feature is helpful if you are troubleshooting a specific problem and require more information about the cause. You can look for events in different categories such as "Application," "System," and "Security." Here, we will focus on the "Security" category of Event Viewer.

NOTE: If you run Windows 10 Home, you will only see successful login attempts (this log is enabled by default in this edition). You have to use Windows Pro edition with the included Local Group Policy Editor to allow full login auditing.

How to Set a Custom Filter In Event Viewer

As mentioned, Event Viewer keeps many logs with a great deal of information, so it may be not easy to find a particular event ID (there could be hundreds of events logged throughout the day). A filter feature in the Event Viewer enables you to create a custom view to see only particular event IDs. We use a filter to see only the IDs of logged events pertaining to login attempts in this example. Right-click on "Custom Views" and select the "Create Custom View..." option to create this filter.
