How to set custom registry entries?

[anceintsz]

To be able to set the opacity to 100%, please?

 

Also how to add the (applicably bought item.key) to the registry, please?

 

Thank you for the GUI, BigM!

 

I would like to know also how to increase the transparency of everything in the windows, too?

 

I would like to know a lot. Please.
