Hi,
I tried the above solution, deleting registry values. All it did was not recognizing my keyboard anymore (or any USB keyboard connect to the PC). I had to put the registry key back to recover a functioning keyboard. The original issue still remains though. I have been missing on and off the follwing keys: "Tab, 1, ², escape and caplock."
I am still looking for reliable options. I have installed Windows 7 and it seem to work. However I have not been using it long enough to know if it is a lucky fix or a steady improvement.
Best.
