How to use PuTTY Client?

Install PuTTY

To get started, you need to download the installation package. For 64-bit PCs, you will want to download the 64-bit version putty-64bit-installer.msi. If you’re only using your computer for basic functions, a 32-bit installed version is usually more than enough. If you want to work with even larger files, or install more programs, then the 64-bit version (putty-x86_64.exe) is a better way to go.
