The cause of the trouble is change. My wife is what I suppose you could call a power user, she pushes the things to the limit out of necessity. After a while, they get full of crap that slows them down and eventually screws the O/S. I spend hours sorting and cleaning the laptops on a regular basis. This time I could not straighten out the 7 install after days of trying. I rarely fail to get the wife's and others machines working like new again, this time it was beyond repair.
The best I could get it to do was update it's self to 10, much to my ladies disgust! (No prompting from me, I promise) Even that update took many hours to load, I was starting to believe that there was a hardware fault. OK it seems to have sorted it's self now and is working fine.
It will take time for my wife to get used to 10, but she "ain't got no choice", to use the usual local vernacular. I will just have to put up with the ear bashing about how badly designed Windows is. It was the the same with XP and 8.1 but very little moaning about 7, strangely enough. Thanks all, problem solved, well at least for the laptop. :eek:
