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

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.

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.
