Nearly a billion PCs are still running Windows 10, and half are too old to upgrade

Windows 10 is still on many devices but in case if these devices are not supported for Windows 11, the force upgrade may also affect the productivity of these devices. 

As per Microsoft, devices that do not meet the minimum system requirements for Windows had 52% more kernel mode crashes. Devices that do meet the minimum system requirements had a 99.8% crash free experience.

Worth to mention here, Windows 10 users can also enroll into Extended Security Updates to continue getting updates for one-more year as the supported ended:

Outdated hardware may not support critical security updates, leaving systems exposed.

Keep using Windows 10 if it still works fine for you.

Performance issues: Older hardware combined with outdated software can result in slow, unresponsive, or unstable system behavior.

Compatibility problems: New applications and features might not work correctly or at all on outdated hardware.

Missing features: Users miss out on improvements, new tools, and security enhancements introduced in recent updates or Windows 11.

You're right—Windows 10 remains one of the most widely used operating systems globally, with nearly a billion devices. However, many of these PCs are outdated and unable to receive the latest updates, which can pose security risks and limit access to new features.
