A workstation that lags when launching Windows, a file that cannot be opened after an update, a forgotten password on a work account: we all encounter these blockages daily. Mastering the basics of computing and keeping up with industry developments is primarily about avoiding wasting time on these recurring situations.
Computing today covers a wide range, from hardware selection to cybersecurity, including online tools and European regulations.
End of support for Windows 10: what it means for your computer
Since October 14, 2025, Windows 10 no longer receives standard security updates. In practice, this means that every discovered vulnerability remains open on non-migrated machines. For an individual or a small organization, the risk is direct: third-party browsers and antivirus software do not compensate for the lack of system patches.
Before upgrading to Windows 11, check the hardware compatibility of the workstation. The TPM 2.0 module and the type of processor are the two most common blocking criteria. On a computer older than five years, the upgrade may require a motherboard replacement, which often costs as much as a new machine.
For those who want to delve deeper into the subject and discover regularly updated resources, the presentation of the Tic et Net site covers software and hardware topics with a practical angle. Alternatives also exist: some Linux distributions (Ubuntu, Linux Mint) work on older hardware and provide a complete office environment, including a browser and productivity suite.
Free online tools to manage files and data daily
We often use three or four software programs without ever exploring their advanced functions. The problem is not the lack of tools, but their underutilization.
Office suite and cloud storage
Google Docs, Sheets, and Slides cover basic office tasks without installation. The associated cloud storage allows access to files from any device. LibreOffice remains the offline reference for those who prefer to work without an internet connection.
Synchronizing files between the cloud and a local disk prevents data loss. A synchronized folder on the desktop acts as a safety net: if the hard drive fails, the documents remain accessible online.
Password management
Reusing the same password everywhere is the riskiest shortcut in computing. A password manager (Bitwarden, KeePass) generates and stores unique credentials for each account. The setup takes about ten minutes, and the security gain is immediate.
- Bitwarden: open source, device synchronization, complete free version for personal use
- KeePass: local storage only, suitable for those who do not want to entrust their data to a remote server
- The browser’s built-in manager: convenient but limited, as it is tied to a single browser and less secure in case of workstation compromise
Cybersecurity and regulation: NIS2 and AI Act in practice
Cybersecurity is not just about installing antivirus software. Two European texts concretely change the obligations of organizations and, by extension, the tools we use.
NIS2 Directive and security obligations
NIS2 aims to strengthen cybersecurity across a wide range of organizations in Europe. In France, the national transposition of the text has been delayed, but the affected companies should prepare their compliance without waiting for the final vote. Incident management, backup policy, team awareness: these projects take time to implement.
For small organizations, the concrete challenge is to document their procedures. Knowing who does what in case of an incident, where backups are stored, how to isolate a compromised workstation: these reflexes should be prepared before a crisis, not during.
European regulation on artificial intelligence
The AI Act applies in stages according to the risk level of each use. Using an AI tool can now raise compliance questions, not just productivity. Automated CV sorting software or a customer service chatbot fall into different risk categories.
This progressive timeline means that information about digital tools must be dated. A guide published six months ago may already be outdated regarding AI-related obligations. Checking the publication date of an article before relying on it is a basic reflex often overlooked.
Maintenance tips to extend the lifespan of a computer
A slowing computer does not necessarily need to be replaced. A few regular operations are enough to maintain decent performance over several years.
- Deleting temporary files and clearing the browser cache every month frees up disk space and reduces startup slowdowns
- Disabling startup programs via the task manager (Windows) or system preferences (macOS) significantly shortens boot time
- Checking the hard drive’s status with a diagnostic tool (CrystalDiskInfo on Windows, Disk Utility on macOS) can detect an impending failure before losing data
- Adding RAM remains the most cost-effective hardware upgrade for a workstation older than three years, provided the motherboard allows it
The useful lifespan of a workstation also depends on its usage. A computer dedicated to office tasks and internet browsing lasts much longer than a machine used for video editing or resource-intensive development software.
Keeping the operating system and software up to date remains the simplest measure to combine security and stability. With the end of support for Windows 10, this habit becomes a structural choice: to migrate, change systems, or accept an increasing risk.
