You can take precautions against others using your PC, but sometimes, you don’t think it’s necessary. You can trust your family and friends. And the people you work with won’t snoop on your online activities.

Yet things aren’t right. Your laptop isn’t where you left. Your desk is a mess.
Has someone secretly used your PC? What have they been looking at? Nearly everything you do leaves some kind of trace on a computer. You just need to know where to go in order to find that evidence.

Knowing where to start can drastically reduce the amount of time it takes to find the culprit. Here’s how you can tell if someone logged into your computer without your permission.

1. Check Recent Activities

You should already know how to look at recently opened files. Windows introduced this as an easy way to go back to whatever you’ve been working on or looking at. It’s especially handy if you’re adding an attachment to an email or uploading to a blog. But you can also use this feature to check if someone else has been accessing your files.

Just head to the File Explorer by either opening Documents, This PC, or pressing Windows key + E. At the top left of the menu, click on Quick access. You’ll be able to see what’s been opened, so look for anything you haven’t accessed yourself.

Alternatively, you can check files opened in individual apps. If you think someone’s snooped on a PowerPoint presentation you made, check Recent in that program.

2. Check Recently Modified Files
However, anyone can wipe recent activity from your machine. Just left click on Quick access > Options > Clear File Explorer History. If your recent activity has been deleted, this is at least a sign that someone has used your PC. But how can you tell what folders they’ve opened?

Navigate back to File Explorer then type “datemodified:” into the search field at the top right. You can refine by a date range. It’s probably most useful if you click on Today, but you can go back a whole year too.

You’ll see a list of files that have been accessed—as long as something was changed. Let’s hope you’re lucky enough that your PC automatically saved an item while the snooper was at work. Check the times listed and narrow down when you were away from your device.

3. Check Your Browser History
Okay, everyone knows you can easily delete your browsing history. But if someone used your PC in a hurry, they might’ve forgotten this step.

Google Chrome has the biggest market share, so it’s most likely that whoever went on your computer used that. Click on the vertical ellipsis in the top right corner then Historyand see if anything’s amiss.

Don’t rule out other browsers though. If your PC has Edge, go to the ellipsis then Favorites > History. You can use a similar method if you still have Internet Explorer installed. Firefox users should click on the menu, followed by History > Show All History.
