Introduction

PuTTY is an SSH and telnet client that runs on Windows, Linux and UNIX. This terminal emulator establishes a TCP/IP connection and works with multiple network protocols.

Helpful Hint

Did you know that the TTY in PuTTY is a UNIX terminal command that prints the name of the terminal you're connected to? It's derived from the word TeleTYpewriter.

Step 1: Download the installation package

Launch your favourite browser and download Putty from the official site: www.chiark.greenend.org.uk/~sgtatham/putty/latest.html

Click putty-version-installer.msi if you're on a 32-bit computer or putty-64bit-version-installer.msi if your PC has a 64-bit processor.

Going Deeper

Tip: All newer (>2015) computers have a 64-bit processor except for the budget ones. You can determine whether your PC is 32-bit or 64-bit by right-clicking on the (This PC/my computer) icon on your desktop and choosing properties.

Step 2: Installing PuTTY

You must have administrative privileges to install PuTTY. Launch the installer by double-clicking the downloaded file. Click "Next" throughout the wizard to Install PuTTY with all the default (recommended) options. You may change the installation directory. You can choose whether to create a desktop shortcut and associate PuTTY with .ppk files (private keys for connecting securely to other computers). These options are enabled by default.

You may get this prompt depending on your current UAC settings. Click "Yes".

The installer will run for a few seconds. Untick "view the README file" and click "Finish".

Congratulations! You've just installed PuTTY.

[OPTIONAL] Step 3: Launching PuTTY

Run PuTTY by double-clicking on its newly created desktop shortcut or by searching "PuTTY" on the Start Menu.
