The more serious challenge, though, will be one of user inertia. At last count, estimates are that there remain 900 million PCs running Windows 10, of which only 400 million are not technically capable of the leap to Windows 11.

– Some 65% of Windows users are still using Windows 10. – Some PCs that run Windows 10, and are still fast enough for their owners, do not support Windows 11. To upgrade to the new software, the user would need to purchase a new computer.

Tech support won't be offered for Windows 10, but security updates will roll out past 2025 with the Extended Security Updates option.
