As someone once remarked "On XP everything looks as though it should go MOO! when you click on it."
After growing up with Amiga and then MacOS, I only really encountered Windows XP when I started my first proper job.
Couldn’t believe that that was the default OS for professionals and businesses. With all the chunky graphics and bright colours it looked so childish - like it was designed for preschoolers, not 98% of the world’s computing.
There was even a puppy animation when doing a search.
You could easily switch it to look like earlier versions of Windows, however. I miss that ability in 8.1 and 10; up through Window 7, I could make my desktop look like Windows 95 if I wanted to, and sometimes I did. Nothing like having a colleague walk up to you in 2017 and asking you, "is that Windows 2000?"
