Software needed to read Dvd key of computer?

I installed windows 7 professional only 6 months ago and have lost the DVD.
Is there any software that will work and read the key off my computer?
Magic Jellybean does not work sinc the key is encrytped.

 

Try using Speccy by Piriform it will show you the code under operating system.

Tried the software and it does not show or read the windows 7 64 Bit professional key that was installed on the computer. Thanks for your help.
