In a nutshell: Researchers warn that up to 240 million PCs could wind up in landfills after Microsoft ends support for Windows 10. The rationale here is that Windows 11 hardware restrictions will render all of these computers obsolete. However, older computers have been going obsolete for decades, and current recycling efforts are much more robust than in past years. So, will it be a real problem?

Windows 11's strict hardware requirements have received their fair share of controversy since launching in late 2021. Initially, Microsoft warned of compatibility issues, which didn't go over too well, and saw users finding ways around the hardware checks. It's raising further concerns as Windows 10 approaches end-of-life (EOL) status.

Technology research firm Canalys reports that when Microsoft sunsets Windows 10 in 2025, it could send as many as 240 million PCs to the scrap heap. Reuters estimates the dump would equate to 480 million kilograms of e-waste. For perspective, it adds that such a dump is equivalent to about 320,000 automobiles.

"Microsoft's decision will worsen the industry's e-waste problem and highlights the role of OS vendors in enabling circular IT models," notes Canalys. "Microsoft's Windows 11 will help support a struggling PC market as customers prepare for another refresh cycle – but the termination of Windows 10 support could prevent hundreds of millions of devices from getting second lives, leaving many liable to end up in landfill [sic]."

However, the entirety of 240 million computers will not likely land in garbage dumps in 2025.
