Microsoft’s decision to stop free, routine security updates for Windows 10 on October 14, 2025 has done what product lifecycles often do quietly — it turned a software milestone into a public-policy flashpoint about the scale of electronic waste, the limits of the right to repair, and who...

Microsoft has turned the page: on October 14, 2025 Microsoft officially ended mainstream, free support for Windows 10, and with that decision millions of PCs worldwide moved from a vendor‑maintained security posture into one that requires immediate user action to remain safe and supported...

Microsoft’s big-splash claim — that “Windows 11 PCs are up to 2.3× faster than Windows 10 PCs” — landed in a months‑long marketing push around the end‑of‑support deadline for Windows 10, but the assertion needs unpacking: it’s true in specific benchmark comparisons on modern hardware, and...
