Thanks I'll maybe give that a go. I phoned Microsoft customer service & a helpful lady told me to type SLUI 3 in the start box I did & got a large dialogue box with an instruction to type in my product key. This I did it ran a check & said my product was validated. Great - I thought & thanked her Today when I booted it up after a few minutes I got the not a genuine windows 7 box again.Great!! I ran the validation again & once again it said validated. Obviously it won't last so I'll try the procedure you indicated.
