How to install putty on windows 11

PuTTY is a lightweight SSH, Telnet, and serial terminal for Windows; installing it on Windows 11 gives you a reliable client for remote server access and secure console work.

Step 1: Download the PuTTY Installer

Download the official PuTTY MSI installer from the PuTTY website to get the latest stable Windows build.

Start-Process "https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html"

Step 2: Run the MSI Installer

Run the downloaded .msi, follow the installer prompts, and accept defaults (or choose an install folder) to install PuTTY and its utilities.

Start-Process -FilePath "C:\Users\YourUser\Downloads\putty-<version>-installer.msi"

Step 3:  Install via Chocolatey

If you prefer package-managed installs, use Chocolatey to install PuTTY from the command line for easy updates.

choco install putty -y

Step 4: Add PuTTY to PATH

If you want putty and related tools available from any PowerShell or CMD window, add the install folder to your system PATH.

setx /M PATH "%PATH%;C:\Program Files\PuTTY"

Step 5: Launch PuTTY and Configure a Session

Open PuTTY from Start, enter the host/IP and port (usually 22 for SSH), choose SSH as the protocol, and save the session for quick reuse.

Start-Process "putty"

Step 6: Use Pageant for SSH Keys

For key-based authentication, load your private key into Pageant (PuTTY’s SSH agent) so PuTTY authenticates without prompting for a password.

Start-Process "pageant" -ArgumentList "C:\path\to\your\privatekey.ppk"
