How to Know If Someone Used Your PC and When

In this guide i will explain How to Know If Someone Used Your PC during 

your Absence and When? While you could always set a password or install 

something like Prey ahead of time, you might be in a position where you 

suspect someone's already used your computer without your permission. 

Checking your computer's built-in logs is a great way to do that after the fact.

So lets start:

Method 1 :- Windows Default Logon Auditing

First you need to be enable the logon auditing on your computer through this:
  • Open "start menu">>Type "run"(or press windows key+R) and press

    "enter" and this box will pop up:
  • In this box write secpol.msc and navigate to "Local Policies" and choose

    "Audit Policy".
  • In the right-pane side select the “Audit logon events ”  and enable both

    Success and failure option. Click on Apply the settings.

 After enabling this setting, Windows will log logon events – including a 

username and time – to the system security log.To view these events:
  • Open the Event Viewer through opening start menu type "event viewer"

    and press enter to open.
  • Navigate to the Windows Logs.
  • Then search for Security category in the event viewer.

Look for events with event ID 4624 – these represent successful login


To see more information – such as the user account that logged into the 

computer – you can double-click the event and scroll down in the text box.

 Method 2 :- Use the Tool WInLogOnView

WinLogOnView is a simple tool for Windows Vista/7/8/2008 that analyses the 

security event log of Windows operating system, and detects the date/time 

that users logged on and logged off. For every time that a user log on/log off 

to your system, the following information is displayed: Logon ID, User Name, 

Domain, Computer, Logon Time, Logoff Time, Duration, and network address. 

WinLogOnView also allows you to easily export the logon sessions 

information to tab-delimited/comma-delimited/html/xml file.

and this is considered easier than the other as shown in the previous screen
