Which keys are wrong Mark ?
Is it the " and @ the wrong way round ?
If so then you have got your keyboard set as a US english keyboard not UK english one.
Just go into Control Panel, Regional and language Options, Languages then Details and remove the US one and Add the UK one.
It will say you cant remove the US one as its in use but will be removed on next restart.
Just reboot and things should be ok :doggie:
