Yet another very long update - and it seems each update causes more waste of time and more problems. The latest Windows 10 does not seem half as useful as even the old operating systems such as Windows XP. There are several programs that I was using which no longer run and I now get duplicate unauthorised videos running, which slow the system down. The useful applications such as defrag and scandisk seem to have been disabled. Why get rid of so many things that work and replace them with things that do not work properly?
