Microsoft has announced that Windows 10 EOS (End of Support) will occur in October 2025. After this, the operating system developer Microsoft will no longer provide new security and feature updates or technical support for devices running Windows 10.<\/p>

Microsoft has, however, given Windows 10 users the opportunity to purchase a three-year extension to security updates by purchasing the Windows 10 Extended Security Updates program from Microsoft, which extends support for security updates by a maximum of three years. However, ESU does not bring new features or functionality to your device, but only applies to security updates. Microsoft emphasizes that ESU is not intended as a long-term solution, but rather as an interim step in the Windows 11 transition. If you have a device that does not allow you to update from Windows 11 due to hardware requirements, updating your device in the near future is very timely.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Each device manufacturer provides security updates for their network devices or operating systems for a predefined period of time. When a device or software stops receiving new security updates or technical support, it has reached the end of its lifecycle. This is called \u201cEnd of life = EOL\u201d. When security updates and technical support end, devices and old operating systems become vulnerable to security threats because new vulnerabilities are no longer fixed by the manufacturer. Criminals have long searched the Internet for devices with vulnerabilities and targeted them with attacks, hoping to gain access to the user\u2019s files by exploiting the vulnerability.<\/p>

Keeping systems and software up to date is very important for information security. Whenever possible, it is a good idea to automate device updates so that information security is not left to someone\u00b4s good memory. Outdated antivirus software may not protect the user from malicious websites, and the user may accidentally download a file that contains malware. This can, for example, spy on the user's activities and save login credentials, which can be used to encrypt the device's files.<\/p>

By using an unpatched device, you can give a criminal access to your data or, on the other hand, give the opportunity to use the device in, for example, denial of service attacks. The criminal can also gain access to other devices on the same network. Remember that the criminal can also use the device they have taken over to send phishing messages or emails to other users. In terms of information security, the best possible thing to do is to get a new device for which security updates are available.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
