How to lock your screen in Windows 10

Every day we work with Windows 10, whether at home, study or office, and one of the most effective ways to prevent unauthorized access to it (and therefore the information stored therein) is by blocking the computer every time we are away. Many times we go to lunch, take a breath and leave the equipment as is, making it vulnerable to unauthorized people accessing it and being able to view files or make changes to it.

Our computer is one of our main information banks that we use daily. Other devices such as mobile phones or tablets also contribute to transferring large amounts of information that we are storing almost without realizing it.

This a priori does not seem to have any negative connotation, but if we begin to analyze from a security perspective, we enter certain doubts and concerns. Saving information on our computer can be as comfortable as it is dangerous . We tend to think that we are in a safe place because we surround ourselves in an environment where we know people but we always have to stay ahead of terrible events.


Think for a moment that you have very important projects or jobs stored on your computer that you have been working on for months, you get up from your post for a moment, and when you return someone has accessed your computer and erased everything. The scare can be very great and the displeasure after so many hours of work even more, and all for not having saved it 2 minutes before. Think that you are working with your personal information and that no matter how much trust you have with someone, your safety comes first.
