You may have seen one of these “slideshows” before but if it’s been a while since you’ve seen/used the earlier versions of Windows, this can be a trip down memory lane. The Hongikat blog has screenshots of all major Windows versions since version 1.01.
Windows 1.01 (1985)
Windows 3.1 (1992)
I used Windows 3.1 until 2004 on my bedroom PC so this, admittedly, doesn’t take me back that far.
