Today, Microsoft announced the official end of mainstream support Windows 8.1 operating system. This means that Win8.1 will not get regular feature/security updates in the future and will only get Microsoft patches in the face of critical and major BUGs.
The extended support will continue until January 10, 2023.
Currently, on the “Assistive Technology” page, Windows 7/8.1 users can still upgrade to Windows 10 free of charge, until January 16th. Taking into account the CPU vulnerability fix Win7 / 8.1 obvious negative optimization, it is recommended that everyone can ascend it.
Finally, incidentally, the extended support for Windows 7 will end on January 14, 2020.
