From the outset, Windows offers us a series of functions related to privacy and security regarding access to the system . But with everything and with it, there may be cases in which other users access it without our permission. That is why we are now going to show you how to check all this on the PC.
And it is possible that we suspect that someone has accessed and is using our computer when we are absent. This is something that can be given both at home and in the office. It is possible that a co-worker, roommate, partner, or anyone else may have access to the equipment without our permission. Obviously this would result in accessing stored personal or confidential information.
It is always advisable to access the system using a password , but someone in our environment may have seen us enter it. In the event that we have doubts, then we will see how to carry out the relevant check. In fact, we have several methods that we can use for these verification tasks, as we are going to see.
Check Windows Event Viewer
First of all, we are going to make use of a very interesting feature of the Microsoft system, the Event Viewer . Here all the events that are happening in Windows are stored, including the login, of course. Therefore, this is a good element that allows us to check if someone has accessed our computer without our permission. We can open this section just by typing its name in the search box on the taskbar.
Next, in the left panel we go to Windows / System Logs . At that time, all the events that have occurred in the operating system will appear in the central panel of the tool. Therefore, we only have to browse through them and look for the last login to check if the time coincides, or not, with the last time we turned on the PC.
Check browser history
We can also use some tricks that allow us to perform this check. Generally, if a non-permitted user uses our equipment, it is very likely that they will use the installed Internet browser . Therefore, in this case we can always take a look at the browsing history stored by it, where the last pages visited are indicated. In the event that they are not the websites that we loaded in the last session, we will have to take the appropriate measures.
View PC USB device history
Another very effective method for these tasks that we discussed is to take a look at the history of USB devices connected to our computer. This allows us to check first-hand if any unfamiliar USB memory has recently been connected to our PC without our consent. To do this we are going to use the system command line.
First of all, we access it by typing CMD in the Windows search box . In the new window that opens now we just have to type the following command:
reg query hklm/system/currentcontrolset/enum/usbstor /s
Take a look at recent files
In this case and as a preventive measure, we can activate a function that helps us to check if someone has accessed our computer. In conceto we refer to the recent files that have been used, which will serve as evidence. To do this, we open the Windows Settings application and go to Personalization.
Next, we click on the Start section and locate Show recently opened items , something that we activate. This way we will see in Start all the files that have been opened in the last sessions with the PC.
