I've been using Windows for over 20 years and I think that I can honestly say that with two exceptions none of the later versions gave me anything that I didn't already have and often confused me by changing the way things work. The two improvement were the ability to cope with long file names - early versions limited you to 8 characters which was a nightmare - back then I was doing consultancy work for several hospitals and trying to come up with meaningful file names with just 8 characters was a nightmare - although even then there was a quickly developed stand alone programme which enabled one to use long names. The other improvement is in Word, early versions of which couldn't cope with big files - I can't remember the level at which it ran out of puff, but it was probably around 100,000 words, perhaps less, whereas now I have a number of documents of over a third of a million words.
