It was Win98 dressed in a clown suit. I still have it on a fossil laptop here.
Prior to this OS, I had never heard "Windows" used as a verb before.
"Windows Me"= "Byte Me".
I still don't know what ME really was. A dressed down NT? A poorly updated 98? A multimedia home version of 2000? It just really can't be classified. 98C was so much better that calling ME an upgrade was LOL funny.
