Over 90% of ransomware attacks target unsupported PCs, highlighting the urgency for users still on Windows 10 to transition to Windows 11. A poll showed that 84% of Tom’s Guide readers are still using Windows 10. Unsupported systems are vulnerable to ransomware and malware attacks, which can compromise personal files and lead to identity theft. Microsoft no longer monitors older systems for vulnerabilities, leaving users unaware of potential breaches. The long-term costs of not upgrading can exceed the investment required for a system that supports Windows 11. To mitigate risks, users should implement antivirus solutions, use strong passwords, and regularly back up critical data.
