What are the risks of continuing to use Windows 10?
Andrei Sabelfeld, professor of Computer Science and an expert in security, shares advice on how to manage older computers and maintain good digital hygiene.
To do nothing is like leaving your car unlocked with the keys inside
As Microsoft ends support for Windows 10, many older computers will no longer receive security updates, increasing the risk of cyberattacks. In a recent interview by Sveriges Radio, professor Andrei Sabelfeld explained security implications for users whose computers run Windows 10.
Here is a summary of what the radio interview was about:
What happened?
'Microsoft will no longer provide security updates for Windows 10. The Windows 10 system is ten years old, and Microsoft is now in the process of phasing it out. Windows 10 computers will still work, but new vulnerabilities will no longer be fixed.'
Consequences?
'Hackers constantly look for vulnerabilities, and systems without security updates are particularly exposed. To do nothing is like leaving your car unlocked with the keys inside. At any time, anybody can jump in and drive away, with all the valuables in the trunk. And on the computer, that means locked files, stolen data, and that your computer can be used to attack others.'
What to do?
'My advice is to update to Windows 11 as soon as possible. If your computer is not compatible with Windows 11, there is actually an emergency solution called Extended Security Updates. You can sign up via Windows settings and then you will receive security updates for another year. However, it is an emergency solution and not a replacement for an update. Furthermore, you should update all the software you have on your computer, make sure that the antivirus is on (Microsoft Defender Antivirus), make sure that there is a backup of your files – preferably in the cloud – and be careful with e-mails and downloads.'
What does digital hygiene mean?
'In general, it is a good idea to review the programs and apps you use, both on your computer and on your mobile phone, and keep them up to date. One tip is to use password managers instead of having to remember passwords yourself, enable multi-factor authentication, and be vigilant about phishing. Another tip is to check out resources like Surveillance Self-Defense from the Electronic Frontier Foundation, a good source for digital hygiene and secure communication.'
