Hi guys can anyone tell me how I can make a simple bat file that will open up this reg key

"HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlC lass{4D36E965-E325-11CE-BFC1-08002BE10318"

I usally have to delete the upper and lower filters inside this regkey for the optical drive to show up again, so it would be easy if I can just perss the bat file and go stright there.

As seen in the following you can make your own or just use the one made by Doug Knox:
