The interesting twist to these Windows 10 numbers is the 400 million or so users that don’t have the right hardware to upgrade. While there are various options to upgrade on a non-compatible PC, Microsoft has just firmed up its warning that doing so could stop further updates and even invalidate any hardware warranties still in place.

With the end date for Windows 10 less than a year away, people still using that operating system will need to start preparing to enter the Windows 11 era. And Microsoft is placing a hardware requirement on the current OS that could pose a problem for those of us using older machines.
