Hal Hill, I would advise to stick to win7 all the rest that followed are just full of apps and ads. I had a terrible event just recently, Windows 10 offered me a free UPGRADE, not update. I presumed this was like the 8 to 8.1. Well to cut a long story
short, it corrupted my files and left my pc in a repair loop which was unescapable.
Microsofts own tech tried for a long time to sort out the problem and then told me I needed outside assistance because they would need to have my pc next to them. Well I was informed that the UPGRADE had damaged files, they tried to save my important files
and bless them they succeeded. I would warn all, if you are going to backup (which I would STRONGLY RECOMMEND, then please check first if any of your files are damaged. To fully get my system back I had to buy another Win10 OS disc, maybe this what microsoft
really wants!!
