As the article notes, the increase seems to be driven mainly by users in Asia, where recycling and reusing older hardware is quite common. I wonder if third-party companies are offering extended security patches there, which could make affordable second-hand Windows 7 machines more appealing for people who just need them for browsing or light tasks. It would certainly make sense given recent fiascos and Microsoft’s current stance on AI, especially with generative AI being used to develop system-level code.
Possibly from people booting up 15 year old laptops to see if they‘re still running so they can install linux on them before trying it on the big machine. Yes, this is my made up narrative but I believe that more than in a Win7 comeback.
