- Microsoft cautions that unsupported endpoints are prime entry points for ransomware, a risk that extends from homes to businesses.
- Consumers can opt into a one‑year Extended Security Updates plan via a Windows Update prompt, with a free route tied to backing up settings to the cloud or alternatives to pay or redeem loyalty points, and must move to Windows 11 by October 13, 2026.
- Forbes reports that as many as 400 million PCs could be at risk without ESU enrollment, though public data on upgrades and sign‑ups remains unclear.
