Windows 10 Support Ends : Windows 10 has stopped receiving free updates from Microsoft since 2025, but it is still eligible to receive some critical updates for free.
Utilizing Extended Security Updates (ESUs) : Since some EDUs and ENTERPRISEs can get ESUs, they join the insider program or use dirty tricks from Microsoft to keep themselves safe.
Migrate to Supported Windows 11 Hardware : If the hardware is supported for Windows 11, one can install Windows 10 and obtain firmware and patch support from it.
Microsoft Defender + Controlled Folder Access : Even without full support, Defender is now being supported. Enable all protections, including ransomware and a firewall.
Use Open-Source Tools : Tools like 0patch offer micropatches for vulnerabilities that Microsoft no longer covers, without bloating your system.
Browser + Use Secure Extensions : Use Brave, Firefox ESR, or Edge with HTTPS Everywhere, uBlock Origin, and WebSandbox.
Create System Images and Update Offline : Every month, download and manually install a new cumulative update offline, schedule backups to mitigate any additional risks.
Use Lightweight Linux for Secret Work : Use a dual-boot Linux system for tasks such as banking, work logins, or online shopping. Many Linux distros run well on Windows 10-era hardware.
No Pirated Updates or Unverified Tools, Please! - Avoid dark scripts or cracked ESUs, as they may be malware airdrops. They put your security measures at risk.
