Windows 8.1 is reaching end of life next week, which means it will stop receiving security updates and technical support. Of course, Microsoft recommends upgrading to Windows 11, ideally on a new PC.
Are your PCs running Windows 8.1? You might want to consider upgrading them to a more modern OS like Windows 10 or 11 soon, as Windows 8.1 will reach its end-of-support date exactly a month from now.
