There will be no windows wallet until ZEC releases a windows wallet so that can be copied too.
Dev's cant figure out how to make the (Z) address for zero knowledge transactions work. neither can Zcash dev's.
If I were you I'd switch to (ZHS). Why? they are ranked higher (currently 336 at time of posting) than Zdash (currently 607 at time of posting), have a working windows wallet, No premine, No founders 20% fee, for now no GPU mine but once they open mining pool the GPU mining will give it an upside pop.
The CPU mine makes it fair for even small miners and at home guys with their shitty laptop and keeps the huge farms from dumping the shit down to zero just to pay their eletric bills.
Hey ZDASH...fucking around with your signature logo and tagline BS and develop something for your coin.
