when i bought the laptop it came with windows ME.
when i bought the desktop it had winME installed on it, but i didn't get any install media and there was no way the cost of windows was included in the desktop's price at the cost i got it, so i suspect i've only paid for windows once. of course the first thing i did with that desktop was wipe windows.
i have got illegal copies of windows 98, windows 2000, office 97 and office 2000 but i don't have those installed anywhere and actually i don't even know where they are (so maybe i don't have them).
Oh yes! also i bought a copy of windows 3.11 and MSDOS 6.22 second hand for
