As we know most of new coins dont come with Windows wallets on launch or even long after it (look at ie Ethereum).
Zcash launched with lots of trouble for miners and of course no Windows wallet.
But the day has come, since yesterday we can use it natively on windows with the beta release.
Download from https://zcash4win.com/
sha256 hash of the installer file, zcash4win-1.0.5.msi is:
Navigate to %ProgramFiles%\zcash4win\zcash4win.exe
It doesnt self create the shortcut so you need to go to the folder manually after installation.
Run it and Wait
Now on the first run its downloading an really big file. Since alot of people are on it now - you may just go and browse Steemit while waiting.
Start Using It
Now you are all set, copy all keys and use this nice GUI wallet!
