Txs Walker for your reply,
Problem solved......but in a strange way!
I loaded UWT, (ultimate windows tweaker), and after hours of trying different things I found if I clicked on a few items then set each page to default again and rebooted all returned to normal.
Each page had to be done individually, ie set page 1 to default, reboot, set page 2 to default, reboot etc etc. Dunno how, why or what, but it worked!
