Overview
- After the cutoff, Windows 10 will still run, but security patches, feature updates, and official technical support stop.
- Financial Express reports roughly 400 million active installations remain on Windows 10, raising concerns about increased cyber risk.
- Windows 11 enforces TPM 2.0, Secure Boot, UEFI and supported CPU requirements, and many PCs can qualify by enabling TPM and converting MBR to GPT before switching to UEFI.
- For devices that cannot meet requirements, options include a paid Extended Security Updates program for a limited time or an unofficial Windows 11 install that bypasses checks, each with support and security trade-offs.
- Microsoft 365 apps continue to work on Windows 10 for a period, and reports describe differing ESU timelines, making early migration planning essential.
