Click on Start/Windows Logo and type `cmd` once there type `start %AppData%\`. It will open the explorer in that directory. Create a new folder called "BTCPrivate" and a text file. Open the text file and save as as `btcprivate.conf` (be sure you remove the txt extension) in the directory. An empty file is sufficient
Run start-wallet.bat and the blockchain will begin to be synced. After it is synced it will begin mining blocks. If you don't wish to mine remov the -gen option from the batch file.
Now that you have your node up you can use `btcp-cli.exe` in cmd to make RPC calls to your node (i.e `btcp-cli.exe -testnet getinfo`).
