I started a programming gig, and they gave me a Win98 box. I spent a week whamming on VisualCeePlusPlus, and experiencing frequent lockups. Then at a meeting they asked me how I liked Win98. "I have found it's very stable if you only run one application at a time."
I didn't figure everyone would laugh. As an old Unix and Amiga guy, I had no idea that this generation had been advertising Win95 as if it were "the first widely-used desktop that supports multitasking". Sigh. A couple weeks later WindowsNt went in. I took to calling that "Windows NUT".
