What is the ‘blue death screen’ of Windows and how long can the computer block

This Friday, July 19, computers all over the world started with a blue screen as a background, a disturbing message and without the possibility of gaining access to the operating system, that is, without being able to do anything. This problem, caused by a crowdstrike update, a tool with which the Malweares the cloud of the cloud of the Microsoft System And he has paralyzed the computer activity of airports, media, banks, hospitals, supermarkets and large (and small) companies around the world.

The problems, according to the Incibe, are caused by a defective update of the software owned by the Crowdstrike CyberSecurity Company, which caused a huge failure in equipment with Windows operating system. It is not a cyber attack. Operators are the necessary information facilitated to reduce the impact of the incident and gradually restore the systems.

What is the blue screen

The so -ly -hand Blue Death Screen or Blue Screenshot (BSOD; Originally and in English: Blue Screen of Death) refers to the screen shown by the Microsoft Windows Operating System When it is not (or threatens not to be able to recover from a system error, when it was the work of Steve Ballmer, when it was the work of the Ballmer’s work screen, when it was the work of the Doodschap Ballmer, this Ballmer’s work screen Message was, writing the Microsoft Systems Division, writing the Microsoft Systems Division cannot be recovered.

Troy Hunt, maker of Havibeenpwnned and regional director of Microsoft, has been one of the first to explain in a thread in X in X and explain what happened early in the morning.

According to some experts, such as Marc Vidal, the update of the ‘antivirus’ crowdstrike was incompatible with Microsoft tonight. And he has biased everything. The simple solution would be temporary, restoring the previous status of the system (this requires technicians and collapsed). The final solution is that in Crowdstrike rewrites the updated software and reinstalls the update. That requires weeks. It is possible that systems will continue to fall because back -up computers will be opened if they have not been able to wear the update, ”he explains on social networks.

Some computer engineers have contributed solutions to solve the problem, such as the Mezcua CHE, an expert in cyber security, in which the steps are performed to restore the system:

Two error screens

​

Two Windows error screens are referred to as blue dead screens, as they indicate, one of them is much more serious than the other:

• A blue death screen is known as a stop error or serious detention fault in Windows XP manuals.

• A blue “real” death screen happens when the core of the operating system cannot be restored from an error and the only action that a user can perform is to restart the system that loses all the work that is not stored, the status of all programs that are being carried out at that time is 1 in danger to the integrity of the file system and the archives itself.

The information on the blue screen of death is in any case not sufficient to determine the error. The screen only shows the point at which the code has failed, which can usually differ completely from the point where the error occurred, making error detection very difficult, if not impossible.

In the worst case, as stated on the same blue screen, the device unit stagnates in an infinite loop: every time the equipment appears, the blue screenshine appears, start again automatically, or, otherwise it is restarted by the user, the blue screenshine appears again, and so on.
