Microsoft will cease support for most versions of Windows 10 on October 14, 2025, while offering temporary Extended Security Updates (ESU) for version 22H2. Approximately 40% to 45% of Windows users globally still rely on Windows 10. The end of support raises cybersecurity concerns as Microsoft will stop issuing updates for vulnerabilities and bugs. Organizations using Windows 10 need to devise migration plans to Windows 11, but the transition can be costly and time-consuming, especially for those dependent on legacy software. Delaying migration poses risks such as regulatory violations, increased IT burdens, escalating ESU costs, and exposure to cyber threats. Organizations should prioritize migrating critical systems, review application support, and evaluate ongoing costs for legacy systems. Bitdefender offers security solutions for Windows 10 environments, including risk management, application control, cloud security, and monitoring services.
