I,m no expert , so when I bought my new computer home with the new Vista version, I was in trouble from the start. I assumed it already had restore point. All the popup screens ask do want to save this, but don't have a yes or a no box. I found out that you have to type the answer yes or no, then press enter on the keyboard.

   I personally do not like Vista.
   I do not remember any popup screens that required you to type yes or no.
