As Windows 10 market share rises, a new warning reveals the security dangers ahead—here's what Microsoft users need to know.

In a recent blog post, Microsoft declared 2025 to be the “year of the Windows 11 PC refresh.” That’s because when October rolls around, official support for Windows 10 is going to end and most users will likely need to switch over to Windows 11 when that happens.

Nearly 80% of businesses and 70% of consumers plan to refresh their PC portfolio by the end of 2025—or so says Microsoft.

Just a few days ago, security researchers warned hundreds of millions of Windows users they’re at risk from a “ dangerous security fiasco .” Microsoft has now confirmed the same, proclaiming 2025 “the year of the Windows 11 PC refresh.” And for 400 million users in particular, that means hitting the stores before it’s too late.

Yusuf Mehdi, Executive Vice President and Consumer Chief Marketing Officer at Microsoft, confirmed at CES that Windows 10 will reach its end of life in October 2025 as initially planned, as reported by Windows Latest.
