Hi,

Long winded I know - but to get a wallet stable on Windows:
1. Get (download) a copy of Virtual-Box.
2. Set up a virtual machine running Ubuntu (its quite simple - lots of guides) - you only need about 20GB space.
3. Install Z-Classic (lots of guides available).
4. Install Swing Wallet.
5. Send coins to yourself.

You could also then run a node from the virtual machine and support the cause!

Note: - especially as you would be running a virtual machine - BACKUP YOUR WALLET - preferably to a paper or offline storage (you can just take note of your public and private keypair).
