Windows 10 is as of today an insecure operating system. One that is installed on 4 out of every 10 computers in the world

by

Today is the last day that Windows 10 will be officially supported by Microsoft. This means that this operating system will no longer receive security updates, and therefore the computers governed by said version will be exposed to security vulnerabilities that are discovered from now on. Windows 10 is too popular. The problem with this operating system going unsupported is that it is still enormously popular. It is true that Windows 11 has already managed to surpass it in share, but not by much. According to data from Statcounter GlobalStatsIn September 2025, Windows 11 has a 48.94% market share in Windows computers globally, while Windows 10 has a 40.5% share. Four out of ten Windows-based computers will use an insecure operating system. Five, without taking into account that one in ten continue to use even older versions: Windows 7 is installed on 9.61% of Windows computers, for example. Windows 11 is the version of Windows with the largest market share, but not by much. It overtook Windows 10 just a few months ago, and today Windows 10’s share is around 40%. Source: Statcounter GlobalStats. Remembering Wannacry. On May 12, 2017, we woke up to the news of a massive cyber attack that we first believed was had affected Telefónica and that it was actually global. The ransomware responsible for the attack, called WannaCryput companies in check from all over the world. The attack took advantage of a vulnerability called EternalBlue present in several old versions of Windows, including Windows XP, which at that time had a reduced market share (5%) but was relevant: it was still relatively used in companies that were exposed. The attack forced Microsoft to release a specific patch for this operating system, and showed how serious it can be rely on an insecure operating system. Payment lifeguard… To mitigate the problem that millions of users will now face, Microsoft offers two paths. One of them is the paying officer. The company has launched calls extended security updates (ESU, for its acronym in English). Although some requirements must be met (such as using Windows 10 22H2), many users can enroll in this program to continue receiving critical security updates. That, according to Microsoft, will allow time “while they make the transition to Windows 11”, which is the ideal solution for all Windows 10 users. This option is designed for business users but be careful, because said program – which in fact will have a total extension of three years – it’s not cheap: It costs $61 per device for the first year, $122 for the second, and $244 for the third. And entering the program later does not reduce the cost. …and free lifeguard. But Microsoft will also offer one more year of free security updates in Europe and the USA. In fact, in Europe, being able to activate that one-year extension of support for Windows 10 is relatively simple: just log in with a Microsoft account to access that option. It is best that you move to Windows 11. But obviously the best solution to avoid problems is to update your computer to Windows 11. It is possible to perform this update for free on Windows 10 computers according to Microsoft’s FAQ. Normally Microsoft requires that the PC or laptop meet certain requirements, but even in those cases it is possible to “skip” those obligations and install a modified Windows 11 with a little trick. Or give Linux a chance. There are other solutions, of course. One of them is to maintain the current equipment, but install some Linux distribution on it. Although that may put some users off, these distributions have been making it really easy for users to do the same things they do on their Windows computers for some time now. Including video gamessomething that Steam’s Proton platform has made possible. There is joy in the sale of PCs. In the third quarter of 2025, 9.4% more PCs were sold worldwide than in the same period of 2024. Source: IDC. The end of Windows 10 is a joy for PC manufacturers. Especially because this is the perfect excuse to change teams, especially in the business segment. Old PCs with Windows 10 are a huge security risk for these companies, which are especially forced to update their equipment or renew their IT fleet. That is also true for many users who take advantage of this circumstance, and that is causing a boost in sales. We are already seeing it: an analysis from the consulting firm IDC shows how in the third quarter of 2025, 9.4% more PCs were distributed than in the same period of 2024.

How to use Flyobe to install Windows 11 without artificial intelligence in computers that do not meet the minimum requirements

by

Let’s tell you What is and how works Flyoobe A tool with which you will be able to update to Windows 11 without meeting the requirements. Because the Windows 10 support end It makes it dangerous to use it from October 14, so it is advisable to update to Windows 11. The requirement that brings to all heads is TPMa chip that must be installed on your computer. Exist Windows 11 install tricks Without this chip, and using this application is another of them. And also, as extra, you can also install a Windows 11 version Without a trace of artificial intelligence functions In the event that you don’t like having it. How this application works Flyoobe is the evolution of a tool called Flyby11, which was designed as Swiss razor to install Windows 11 in computers that do not meet the minimum requirements. In addition to this, it also allows to install it without so many pre -installed applications, including artificial intelligence. It is an open source application, and any user can see their entrails entering their Official Github pagewhere you can see that everything is as they say is, and without traps. It is too A free tool so that anyone can use it. Works using the Windows Server installation variant, which is A method that omits TPM checking. Also omits secure boot and compatibility checks of the CPU. Therefore, use an installation method with which you do not need to keep any of this to use Windows 11. The application does everything automatically. You just ask you to install it and take care of download the iso image of Windowsmount and guide you for the installation. How to install Windows using Flyoobe To install flyobe, you have to enter Your official Github page. Once inside go to the section of Downloads or downloads, where you must download and install the most recent version of Flyoobe, which will be the one that appears at all. Once the installs you can already launch the program. Windows may try to block your update telling you that it is a threat, but you can trust it. Once the application sets, first of all you can Choose between updating without meeting requirements or reinstalling The complete operating system. You can directly add the Windows ISO that you have downloaded or ask that the fall itself. But in addition to this there are many options. In the lower part you will have Several customization customization options. In them, you can choose to deactivate everything related to artificial intelligence, but there are also much more that you can configure. For example, you can create a local account in Windows so as not to have to link a Microsoft, or uninstall applications that come by default in Windows, such as One Drive. You can also create specific configuration profiles for video games, work or safety, customize the Windows design or choose the predeterminate browser. And with this, you can proceed to installation. The only thing you should keep in mind is that Microsoft warns that there is no guarantee of receiving updates when you install Windows with this type of methods, although there are not many alternatives if your computer does not comply.

Windows 10 is one step away from running out of support. Almost half of the world’s computers continue to trust him, even more

by

In just over 40 days, Windows 10 will stop receiving patches and security updates. Microsoft will thus mark the end of support for an operating system that still Almost half of the global market dominates (In Spain, 54%). Windows 11 It has been in the market for several years, but the change has been slower than expected. The countdown is still underway And millions of users apparently have not yet decided how to face the jump before October arrives, although those willing to pay may keep it with extra support. What real options now has the standard user The end of support does not mean that your computer stops working, but it is more exposed. Microsoft offers three main outputs: Make the leap to Windows 11. If your PC has the necessary hardware, the update is free and guarantees updates and new functions. The equipment that does not meet requirements will have to be renewed to continue protected. Pay for extended updates (ESU). With this plan they continue to receive security patches paying an annual fee. It is designed to win margin, not to stay indefinitely in Windows 10. Keep Windows 10 or explore alternatives. Install Linux or using the system without support in controlled environments is possible, but requires assuming risks and planning in the medium term. Compare the situation of Windows 11 with that of its predecessors helps to understand if this slow change is an exception or simply history that is repeated. According to statistaat three years and ten months of life Windows 11 is around 49% of the global market. Windows 10, at that same age, had reached about 57%, and Windows 7 moved in even higher figures, around 61%. At the opposite end, Windows 8.1 barely reached 10%, a reflection of his warm welcome. These data draw a clear pattern: Windows 11 progresses more slowly than its successful predecessors, but leads widely against Windows 10. Everything indicates that the hardware barrier, which leaves millions of old teams out, explains a good part of this rhythm. It is not that users resist by custom, but that the jump to the new generation implies more effort than ever, and that shows in global and European figures. The slow advance of Windows 11 is better understood when looking at the requirements imposed: TPM 2.0 and a closed list of processors leave out millions of computers that were runnings 10 without problems before. For many users, update implies renewing the equipment, and that slows the transition. There are unofficial methods to install Windows 11 on non -compatible PC, But doing so entails risks. The result is a slower adoption and a Windows 10 that is still very alive at the doors of its end. Microsoft Operating Systems Market share at a global level Europe and Spain advance to another rhythm. While the global average shows that Windows 11 is already present in almost half of the teams, in the old continent Windows 10 maintains more than 53% quota and Windows 11 is around 43.9%. Spain follows that same pattern (54% in Windows 10 and 42.61% in Windows 11), with practically traced figures. ANDThe result is a photograph other than the global: Here the version jump progresses more slowly and Windows 10 is still the protagonist at the doors of its support end. Microsoft operating systems market share in Spain Update resistance is not unpublished either, although the current context has nuances. Windows 7 reached its support end in January 2020 with a still significant presence, around 27% of the global market, but already surpassed long by Windows 10. Today the situation is different: Windows 11 leads, but Windows 10 retains almost half of the teams, just over a month of running out of patches and official support.

Physicists believed that the neglect was a useless particle. Now they suspect that it is the key to universal quantum computers

by

Experts Quantum computing with those who have had the opportunity to speak, such as Spanish physicists Ignacio Cirac either Juan José García RipollThey argue that quantum computers will be able to make great contributions when they are capable of amend your own mistakes. The main problem they face in this area is noise, understood as the disturbances that can alter the internal state of the cubits and introduce calculation errors. The strategy for which many of the research groups that are involved in the development of quantum computers are opting for monitoring the operations carried out by the cubits to identify real -time errors and correct them. The problem is that from a practical point of view This strategy is very challenging. Logical cubits represent a way to overcome the difficulty involved in the use of hardware or physical cubits, which are extremely noise sensitive, and, therefore, prone to make mistakes. Each logical cubit is constructed abstractly on several physical or hardware cubits, so that a single logical cubit encodes a single cubit of quantum information, but with redundancy. It is precisely this redundancy that allows to detect and correct the errors that are present in the physical cubits. Anyway, the researchers will have one more tool to deal with the errors of quantum computers. It can even be the most powerful resource that they currently have at your fingertips: the Neglectón. Universal quantum computers are one step closer One of the most promising research fields in this area is topological quantum computing. Its purpose is to protect the delicate quantum information that the cubits work coding it in the geometric properties of exotic particles known as ISING anions. An important note before moving forward: in condensed physics an anion is not the same as in chemistry. In fact, Ising’s anions are quasiparticles that, in theory, arise in some two -dimensional materials. Its existence has not yet been demonstrated experimentally, so they are a theoretical result at the moment. It seems a complicated concept, and it is, but in this article we do not need to deepen much more. What we do need is that Ising’s anions They are presumably much more robustand, therefore, resistant to errors that traditional cubits. In practice this implies that moving some anions around others in a specific way should allow researchers to carry out logical operations with them. This is the reason why they are so attractive in quantum computing. And, in addition, they have another great advantage: this configuration is largely immune to external noise. Ising’s anions are quasiparticles that, in theory, arise in some two -dimensional materials Currently, Ising’s anions are thoroughly investigating in the condensed matter laboratories of the entire planet because they are one of the main candidates to participate in the construction of universal quantum computers, and, therefore, immune to errors. Aaron Lauda, ​​professor of mathematics, physics and astronomy at the University of Southern California (USA), Holds the following: “By themselves, Ising’s anions cannot perform all the necessary operations for a general purpose quantum computer. The calculations they support are based on the ‘braided’ (branding), And they require physically moving anions around each other To carry out quantum logic. For Ising’s anions, this braided only allows a limited set of operations known as Clifford doors, which fall short with respect to all the power required for universal quantum computing. “ Fortunately, the research team led by Lauda has found a way to transform ISING anions into universal structures that are capable of performing any quantum calculation through braided. Its solution for the moment is only theoretical, but its potential is enormous. The surprising thing is that what they propose is to resort to a new type of anion known as Neglectón that was initially discarded when it was “discovered” in the theoretical framework. In fact, Neglelectón has gone from being a mathematical waste to be the new hope of quantum computers. In theory when combining Ising’s anions and neglect, universal quantum computing will be possible through braided. According to Aaron Lauda Only one neglect is needed because it remains in the stationary or static state while the calculations are carried out by braiding Ising anions around them. It is a surprising conclusion. One last note to conclude: The neglect is not a fundamental particlesuch as the electron or the quark; It is a theoretical quasiparticle that arises from the collective behavior of many other particles in a two -dimensional system. Let us trust that it is consolidated as the definitive tool that will allow researchers to carry quantum computing from theory to practice in a robust and efficient way.

Quantum computers will change the world when they don’t make mistakes. This milestone is closer thanks to quantum gravity

by

Some experts believe that all the effort that is being carried out in the field of Quantum computing Not anywhere. One of the members of the scientific community more critical of quantum computers is the Israeli mathematician Gil KalaiProfessor at Yale University. According to this researcher, the increase in the number of states of quantum systems and their complexity will cause them to end up behaving like classical computers, so the superiority of the former will end up evaporating. However, the absence of unanimous support by the scientific community should not tarnish the notable effort and advances that many research groups are doing, some of them in Spanish institutions such as the CSIC and others integrated into the structure of companies that have very bulky resources, such as IBM, Google or Intel, among others. In fact, as expected, the latter defend that the long -awaited error correction will reach quantum computers and will allow them to face a much broader fan of problems than that of current prototypes. Terra Quantum bets on quantum severity to correct errors The main problem facing quantum computers in the field of error correction is noise, understood as the disturbances that can alter the internal state of the cubits and introduce calculation errors. The strategy for which many of the research groups that are involved in the development of quantum computers are opting for monitoring the operations carried out by the cubits to identify real -time errors and correct them. The problem is that from a practical point of view this strategy is very challenging. QMM technology reduces errors by up to 35% in current quantum processors Logical cubits represent a way to overcome the difficulty of the use of hardware or physical cubits, which are extremely noise sensitive, and, therefore, prone to make mistakes. Each logical cubit is constructed abstractly on several physical or hardware cubits, so that a single logical cubit encodes a single cubit of quantum information, but with redundancy. It is precisely this redundancy that allows to detect and correct the errors that are present in the physical cubits. The error correction strategy proposed by the researchers of the Swiss Terra Quantum company is not an alternative to the solutions in which we have just inquired; It is a complement. In fact, as explained in the article they have published in Advanced Quantum Technologiesits QMM technology (Quantum Memory Matrix) Reduce errors by up to 35% in current quantum processors. And, in addition, it reaches 94% fidelity using ten times less cubits than conventional methods. An important note: Terra Quantum’s scientific article has been reviewed by pairs. Terra Quantum has tested its QMM technology in IBM superconductor processors, and works. It only requires adding a quantum circuit that does not alter the architecture of the processor, although it is very ingenious. In fact, its operation is inspired by A principle of quantum gravity which maintains that the space-time continuum can be described as a network of me memory cells. It is a complicated idea, it is true, but the really important thing is that we know that this theoretical concept is the one that has inspired Terra Quantum scientists the design of their quantum circuit of errors suppression. Anyway, this innovation joins the effort that IBM, the MIT and other organizations are making to invite us to tie the future of quantum computers with a very reasonable optimism.

Our computers are literally full, the problem is that it is almost impossible to extract it. Or we believed

Gold is one of the metals with better electrical conductivity. For this reason, it is used in many electronic components, mainly in computers, but also in smartphones or sound systems. The problem is that extracting it from these pieces is very complicated and the cost it means does not compensate. Or we believed. Swiss researchers They have created a method to extract precious metal from a serum protein. Find gold in the trash. The components where gold is used most They are the PCB or printed circuit plates that we find in all types of devices, from computers to smartphones. It can also be found in processors, connectors and HDD hard drives. The problem, as we said, is that the existing methods to extract this metal are very complex and expensive. In addition, it is often necessary to use very toxic chemical components, although that does not stop that many Try it in your own houses. For all this, it is often not worth the effort to the small amounts that are extracted. The extraction process. Whey protein. Researchers at the Federal Polytechnic School of Zurich have managed to extract gold with a new more efficient, sustainable and cheap method. As? With serum protein ‘whey’ (yes, the Gym shakes). To do this, they submitted proteins to acidic conditions and high temperatures. These form nanofibers that are added to a gel and, after drying, forms a kind of sponge. It is not the first time we hear that Whey protein is used for similar purposes. A few months ago China managed to recycle the electric car batteries thanks to the glycine present in these shakes. Who was going to tell us that in addition to getting strong, it would serve to extract gold or recycle batteries. The method. The researchers used 20 computer base plates, from which they extracted all metal parts and dissolved them in an acid bath that ionized the metals. The next step was to submerge the sponge in the solution. Although there are other metals that adhere to the fibers that form it, the researchers discovered that gold ions adhere much better. Once “captured”, the sponge is heated and the ions are released and can melt to create a gold peep. Cheaper. The 20 motherboards resulted in a 450 milligrams gold cupcake with 91% purity (the remaining 9% was copper), or what is the same: 22 korates. At the current price of gold, La Pepita would have a value of about 35 euros. It is not much, but the researchers affirm that the cost of the materials and energy necessary for extraction is 50 times less than that of gold obtained. The next step is to climb this technology to be able to apply it to the market. Images | Eth zurich In Xataka | Our dependence on lithium batteries is worrying.
