A computer that lags, an update that loops endlessly, a forgotten password: these everyday situations reveal how central computing is in our lives. Mastering a few technical basics can save time, protect personal data, and allow you to take advantage of digital tools without always depending on a technician.
End of Windows 10 support: what it means for your computer
Microsoft has scheduled the end of support for Windows 10. In practical terms, the system will continue to function, but it will no longer receive regular security patches.
Your machine then becomes more vulnerable to exploits used by malware. This is a real risk, not a theoretical one: attackers primarily target unupdated systems because the vulnerabilities are documented and unpatched.
Have you noticed that Windows regularly prompts you to upgrade to Windows 11? This insistence has a technical reason. If your hardware is compatible, migration remains the most straightforward solution. Otherwise, you can find information on the DigiGeek website to assess your options, including alternatives like Linux distributions suited for older configurations.
Check your PC’s compatibility before any migration. Microsoft’s PC Health Check tool indicates whether your processor, memory, and TPM module meet the requirements for Windows 11. An incompatible PC is not necessarily ready for disposal: it can still be useful under a lighter operating system.
Everyday cybersecurity: actions that truly protect your data
The 2025 outlook from ANSSI confirms a clear trend: data theft is on the rise, and ransomware continues to affect organizations of all sizes, including individuals and small entities. Generative AI lowers the skill level needed to produce more sophisticated attacks, as noted by the agency.
In light of this, a few simple habits make a real difference.
- Update your software as soon as possible. Patches fix known vulnerabilities. Delaying an update for several weeks is like leaving a door open.
- Enable two-factor authentication on your sensitive accounts (email, banking, social media). Even if your password is compromised, a temporary code blocks unauthorized access.
- Regularly back up your files on an external drive or an encrypted cloud service. In case of ransomware, you can restore your data without paying.
- Be wary of unusual requests received via email or SMS. A message urging you to act quickly, mimicking your bank or a delivery service, always deserves direct verification with the concerned organization.
These actions require neither advanced technical skills nor a special budget. The majority of successful attacks exploit human negligence, not a hacking feat.
European regulation on artificial intelligence: what already applies
The European AI Act is being implemented in phases, and confusion is common. Saying that “the AI law is in effect” oversimplifies reality.
Some prohibitions and rules regarding general-use AI models are already applicable. Transparency obligations are set for 2026, while rules concerning high-risk systems have been postponed to 2027 or 2028, according to the institutional summary from ANCT.
Why this matters to you as a user
You are likely already using generative AI tools to write emails, summarize documents, or generate images. These tools will gradually need to indicate that content is generated by AI. This is one of the upcoming transparency obligations.
For individuals, this means it will become easier to identify text or images produced by a machine. For a small business using chatbots or decision-support tools, this implies ensuring that suppliers comply with the new rules as they come into effect.
Learning computing online: choosing the right resource according to your level
There is no shortage of free computer courses, but their quality and format vary widely. Before you start, ask yourself a simple question: do you want to master everyday office tasks, or understand how a network or a program works?
Office skills and getting to know your computer
Platforms like those referenced by France Num offer progressive introductory courses designed for beginners. Prefer video courses with practical exercises over long text documents. Direct manipulation anchors actions much faster than passive reading.
Going further with programming or networks
If you want to understand the basics of programming, sites like Zeste de Savoir offer tutorials written by enthusiasts, with a clear educational thread. The advantage of these communities: you can ask questions and get answers tailored to your situation.
In both cases, consistency and practice matter more than the duration of sessions. Twenty minutes daily on a concrete exercise is worth more than a three-hour marathon once a month.
Maintaining your computer for longevity
A computer that slows down is not always a computer that needs replacing. A few regular checks can significantly extend its lifespan.
- Uninstall software that you no longer use. Each one consumes disk space and sometimes resources in the background.
- Physically clean the fans and ventilation grilles. Accumulated dust causes overheating that degrades components.
- Monitor the remaining storage space on your disk. A disk filled to over 90% significantly slows down the system, especially on a traditional hard drive.
These operations take only a few minutes and require no special tools. They prevent many frustrations and unnecessary expenses.
Computing evolves rapidly, with the end of support for Windows 10, new rules on AI, and the rise of cyber threats. Staying informed and applying simple actions is enough to maintain control over your digital tools in everyday life.
