Thanks for sharing your experience. There was another thread where someone had 27 restore points - why are PC's not set to a sensible (say 15%) maximum? Recently on a new Windows 8 Asus, it took me 2 1/2 days to update with all the updates,install Windows 8.1, and getting rid of "windows.old", not to say over 5000 fragmented files. How totally unaware users manage with even new PC's without issues I do not know.
What is ransomware and how do I protect my PC from WannaCry?
