Got in touch with MS help. They advised wiping the hard drive and waiting 24 hrs!

Eventually my brilliant daughter found the issue. Windows 10 had somehow reset my machine so that num lock was turned on by default!!!. This meant my smallish keyboard subbed some numbers for letters in my password!
In Bios, my machine was set up so that num was auto turned off. I have checked the bios and it was not turned on(off). I have reset it so that num lock seems to be turned off for passwords. This is currently working for the password, but when I go into Word or something, number lock is auto turned on (typing on this forum was the same)

Not until you begin typing the password, is it possible to see a little greyed out "eye" icon, that will reveal the letters of your password, ONLY if clicked and held on the mouse.

You live and learn! Took me a day to solve this one
