I have standard 102 key keyboard using the UK keymap, until recently it worked fine, it still works fine if I boot in safe mode or use some form of non-windows (linux boot etc). My software is setup no differently from normal. And the on screen keyboard won't do it either.

Problem being I am unable to creat a back slash character, the button physically works (if I use it and shift I get pipe '|' character.)

Any ideas?
Look at your keyboard layout in the control panel, make sure it's set properly for your keyboard, either QWERTY or AZERTY. I can all but guarantee this is set wrong and it is a profile specific setting.

Just for the record: \ = Backslash, / = Slash. You'll notice that one slopes "Back" against the flow of your typing and the other slopes "forward"...

I would also bet that the keyboard behaves fine at your windows login but not once you log into the system...
