PuTTY is free software. On Windows, use the 64-bit or 32-bit MSI so that putty.exe, puttygen.exe, pscp.exe, psftp.exe, plink.exe, and pageant.exe are installed together. Typical filenames match your CPU architecture (for example a 64-bit installer for current PCs). After installing, follow the How to use page on this site for the first launch and SSH connection.
