Windows 10 security updates end on 14 October 2025, KDE's 29th birthday and also, ironically, International E-Waste Day [1] (you cannot make these things up!). Hundreds of millions of functioning devices [2] will become e-waste. This means manufacturing and transporting new ones, which is perhaps the biggest waste of all: hardware production alone can account for over 75% of a device's CO2 emissions over its lifespan. Free Software is a solution, today, and if we work together Windows 10 could truly be the last version of Windows users ever use!
