Why was Windows 8 so bad?

Windows 8 came out at a time when Microsoft needed to make a splash with tablets. But because its tablets were forced to run an operating system built for both tablets and traditional computers, Windows 8 has never been a great tablet operating system. As a result, Microsoft fell behind even further in mobile.

Which Windows OS is most outdated?

All software goes to heaven. Windows 7 is the latest operating system to reach “end-of-life,” or EOL, and become officially obsolete. This means no more updates, no more features, and no more security patches.
