Windows 7 vs Windows 8

A rather strange question. Since Windows 8 was released on October 26, 2012, the past tense (What [i]was[/i] different) would have been better.

Anyway, https://www.google.com/search?q=windows+8+vs+windows+7 tells a lot. But you might have to actually work with Windows 8 to find out why it wasn't popular.

We don't have any PCs at office, home or shop that runs those anymore.

I can tell you that either can a PAIN IN THE ACUTE ANGLE to clean install today as today's hardware rarely has drivers for these old Windows.

Considering that Microsoft no longer supports either Windows 7 or 8 it seems a little silly to try to do anything with either version, short of upgrading to Windows 10 or 11 (if your computer meets the minimum requirements).
