In Windows 7, is there a way to know if somebody has logged into my account when I was absent?
Specifically, is it possible to know if a person with administrator privileges somehow entered my account (i.e. in order to get into my email etc.)?
The events will be called Audit Success. The Task Category you will be looking for will be "logon"
Hope this helps!
To anyone: Leave a comment if you don't understand the logs. I'll write a tutorial here =)
You'll have a bunch of system logins; they are normal.
What you will be looking for: Event ID 4624 - Successful logons.
Under the general Tab, Look for NEW ID. Ignore "SYSTEM"
Logs to ignore (unless virus login..)
An indication of a login will look like this: (win 8.1) This will probably be different in win 7
Pathfinder's answer of checking the event log will let you know if someone logged into your computer. However, that will not tell you if they logged into another computer with your account. You would have to check that machine, or a Domain Controller to see logins from other machines.
As for email, thats another story. As an Exchange admin, I can read the mail of anyone in our organization. Honestly, I dont know if that access is logged anywhere. Im sure it would be, but that would be only available to Exchange administrators.
Windows 7 Ultimate connected to a domain, but logging in locally.
I just went through the Security event log and realized that the only time I could find "legitimate" logons were for ID 4648. This worked for me.
If you are on a corporate network, this won't work. Corporations have all sorts of automatic logins. I looked at either event 4648 or 4624, and logons are successfully logged even when people are not in the office (and no, no one is sneaking in to log in to PCs). There are thousands of them. I just logged in to the PC one time, and there are 10 activity sources under 4624. I did not log in 10 times. There were 12 logins yesterday under 4648, but no one touched the PC at all that day. So that's not an accurate list of real person logins.
If you want the REAL login info, go to System under Windows Logs, and filter on event 7001. This is successful WINLOGONS. This corresponds to user logins, and excludes system logins behind the scenes. Using this, I found the proper list of real live people user logins to the PC.
But unfortunately it still doesn't tell me WHO logged in. Our company doesn't keep those records as it would be a mile long every day. I look at UserID in the details, and the UserID for me logging in just now matches every other UserID under every login shown. And this is not my PC, so some of the logins are definitely not mine. So I don't know about that part.
