Microsoft Windows users are facing a serious security risk as Windows 10 approaches its end-of-life in October 2025. Around 800 million PCs are at risk of losing critical security updates. ESET has issued a warning, especially in Germany but relevant globally, urging users to upgrade to Windows 11 immediately to avoid cyberattacks, data loss, and other vulnerabilities.
The warning emphasizes that relying on Windows 10 is dangerous, particularly for businesses, as outdated systems are more prone to attacks like ransomware and could lead to legal and financial consequences. Extending support for Windows 10 is possible but costly, and many older PCs won’t meet the requirements to upgrade due to hardware limitations like missing TPM chips.
Microsoft has introduced a $30 one-year extension for Windows 10 support, but this seems to have slowed the adoption of Windows 11, with some users delaying the upgrade. Security experts are warning that delaying the switch to Windows 11 could lead to severe risks as outdated systems become easier targets for hackers.
As October approaches, expect more warnings and pressure from the cybersecurity industry and Microsoft to encourage users to upgrade and avoid these potential threats.
