Every time you log in to your computer, Windows records the date and time it occurred. You can review these records by launching the Event Viewer. However, the Event Viewer displays other system events too, making it more tedious to find the login records. By applying a certain filter, you can hide unrelated records so you can only see the list of times you or someone else logged in to your system.
Find the Login Records
The login records are stored in the System section under Window Logs in the Event Viewer. You can launch the Event Viewer by right-clicking the Start button and clicking "Event Viewer."
Use Filter Settings
Click "Filter Current Log" on the sidebar. This opens a window where you can apply your own filter settings. To filter the list to only show login events, set the Event Sources to "Winlogon" and type "7001" for the Event ID.
