I agree wholeheartedly at 83 I know a bit about computers having used computing since 1970. Development went in fits and starts until Win XP became the standard. Initially it had its faults but now it does everything a desktop user wants. It is for me the ultimate OS as during its long life all the programs I use reached their best performance.
All programs get improvements over time but eventually they can't be improved so to sell another version the functionality must be changed. These changes often make the program less usable. For example PaintShop Pro improved up to version 9 then Corel "improved" it by getting rid of the full screen display of thumbnails. Similar problems mean that the programs I want do not work on later Windows. Since I am not prepared to spend vast sums of money to get inferior programs to run on Win 7 or 8 I must stay with Win XP to get what I need out of computing. When my current PC fails I think I am going to have to move to Linux so I have started investigating it.
