Back in the day my not-so-tech-savvy colleague bought a Windows 8.1 laptop that had a touchscreen. After two days she brought it to me and asked me if I could "rip this hellspawn out of this computer".

Before wiping it we checked if there was anything to backup and the ~30 minutes I spent using Win 8.1 were hideous. It was the only time I ever had to use it, of which I am very grateful.
