It seems people keep asking about the trusted setup and current development in this thread...
Classic uses the exact same trusted setup as Zcash. So you can trust Zclassic as much as Zcash in that regards. (in the OP)
Windows wallet is in the works. There is a lot to do. Right now the main focus is keeping up to date with Zcash and keeping the network running smooth. There are unique projects in the works, but it is all a matter of time and as more developers come on board.
Remember that this project is only a week old. The reason I became interested in it is because of how stable the price is and how motivated the community is for only being around a few days.
