As computer security is becoming more important, it is essential to know if someone has unauthorized access to your Windows PC. Fortunately, there are several ways to identify if someone else is logging in to your PC.

Here are some quick tips that will help you figure out if someone is accessing your PC:

1. Check Your Event Logs

Windows Event Viewer keeps a record of all programs and settings changes that take place on your computer. You can access the Event Viewer by clicking on the Start menu, typing “event viewer” and pressing Enter. Navigate to the “Windows Logs” section and look for “Security” in the list of logs.

If you see any unusual log entries or failed login attempts, that could indicate someone has been trying to access your computer without your knowledge.

2. Set Up an Automatic Lock Screen

If your computer gets idle for a specific amount of time, it should lock itself and switch to the lock screen. To set up an automatic lock screen, go to Start > Settings > Accounts > Sign-in options. Under the “Require Sign-in” section, set the time to a reasonable one, and you’re ready to go.

This way, if someone tries to access your PC while you are away, they won’t be able to do it without your password.

3. Use User Accounts

Having multiple accounts on your Windows PC is a great way to limit access to the computer. People using another account other than you would need a specific username and password to get it. When you’re away, make sure you switch your account by using Windows + L to lock the screen or log-out from the user account.

You can also create a guest account that anyone can use without giving out your credentials.

4. Install a Security Software

Using an antivirus and antimalware software can help you detect if someone is attempting to access your computer from outside. These programs can alert you if there are unauthorized log-in attempts, unusual system changes, and other unusual activities that could indicate malicious intent.

5. Check Your Internet Connections

Open Task Manager by using the shortcut keys Ctrl+Shift+Esc. Go to the “Network” tab to see your network activity. If anyone is accessing your computer with the internet connection, you would notice the peak in network activity.

Another effective way to monitor internet activity is to use a network monitoring tool that provides real-time stats about the connection.

In conclusion, keeping an eye on your computer logs, setting up automatic lock screens, creating user accounts, installing security software, and monitoring internet connections can help you detect if someone is logging in to your Windows PC without your consent. Following these tips can help you secure your computer and sensitive information from unauthorized access.
