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:
