As the clock ticks down to October 10, 2025, Windows 10 users—numbering over a billion globally—are faced with a pivotal transition. Microsoft has officially announced the cessation of support for its most widely used operating system, a move that serves as a gentle nudge for those yet to embrace Windows 11 or alternative platforms.
Windows 10 end of support: what you need to know
Currently, a significant 64% of Windows users remain on Windows 10, while only half that number have made the leap to Windows 11, which was launched in 2021. This disparity highlights Microsoft’s eagerness to usher users toward the new platform, which promises enhanced performance, productivity, and AI capabilities, alongside a fresh design.
However, the end of support for Windows 10 may pose challenges for those who choose to remain with this “Ford Fiesta of the computing world.” Steve Haskew, group director of sustainability and growth at Circular Computing, notes that while Windows 10 won’t abruptly stop functioning next October, users will miss out on crucial updates and protections.
No more patches
“Microsoft will no longer update or ‘patch’ Windows 10, meaning those who haven’t transitioned will struggle with bugs and become increasingly vulnerable to cyber threats,” Haskew cautioned. James McQuiggan, a security awareness advocate at KnowBe4, echoed these concerns, explaining that cybercriminals are likely to exploit vulnerabilities discovered after the product reaches its end of life, knowing that no patches will be forthcoming.
Additionally, organizations must consider compliance risks, as many industries mandate the use of supported software. Non-compliance could lead to penalties, while unsupported applications may widen the attack surface for potential cyber threats. McQuiggan emphasized that Windows 11 offers enterprises enhanced security features, including zero-trust architecture and better integration with modern cybersecurity tools.
“While the cost of transitioning may seem daunting, the return on investment is swift compared to the potential expenses associated with a cyberattack or regulatory fines stemming from outdated software,” he stated, reinforcing the importance of moving to Windows 11 for improved security and reduced risk.
Sustainable upgrades
Haskew also raised an important environmental concern: the potential surge in electronic waste as users with incompatible hardware may need to dispose of aging computers. Microsoft outlines the basic system requirements for Windows 11, which include a compatible 64-bit processor with at least 1 GHz and two cores, 4 GB of RAM, and 64 GB of storage, among others.
To facilitate the transition, Haskew recommends utilizing Microsoft’s PC health tool to determine device compatibility for a free upgrade, which should take about an hour to install if eligible. “Generally, you are looking for Intel Core i5/8th Generation and above supporting a TPM2.0 chip,” he advised.
For those whose devices do not meet the requirements, alternatives exist, such as switching to Google’s OS Flex, which can transform old Windows-based devices into Chromebooks. Haskew underscores the importance of backing up files before making any changes to avoid data loss and encourages responsible recycling of any unwanted equipment, suggesting users contact their retailers for options or consider donating to charity.
