I have decided I do not now want it, but it doesn't tell

Anyone know how ?

There does not seem to be any way back. Luckily I have
laptops and another PC with most of the things I need to
keep on them.
But it has been interesting to see what Windows 8 is like -
a kiddies picture book is the best description I can think
of. Presumably Microsoft have decided to dumb down
their OSs to match the trend in western educational standards.
I'll be staying with XP pro as long as possible.
