How do I remove PuTTY from Windows 10?

PuTTY is a popular free and open-source terminal emulator, serial console, and network file transfer application. While incredibly useful for connecting to remote servers and managing network devices, there might come a time when you need to uninstall it from your Windows 10 computer. This article will guide you through the process of removing PuTTY thoroughly and effectively.

Understanding PuTTY and Why You Might Remove It

PuTTY is often used by system administrators, developers, and IT professionals to establish secure shell (SSH) connections, Telnet connections, and even serial connections. It's a lightweight and efficient tool. However, you might want to remove PuTTY if:

• You no longer need its functionality.
• You've found an alternative tool that better suits your needs.
• You are performing a system cleanup to free up disk space.
• You suspect it might be causing conflicts with other software (though this is rare).

The Standard Method: Using the Windows Apps & Features Settings

The most common and straightforward way to uninstall PuTTY on Windows 10 is through the built-in "Apps & features" settings. This method removes the program and its associated files that were installed by the installer.

1. Open Windows Settings:
   • Click on the Start button (the Windows icon in the bottom-left corner of your screen).
   • Click on the gear icon (Settings) to open the Windows Settings app.
2. Navigate to Apps:
   • In the Settings window, click on "Apps".
   • This will open the "Apps & features" section.
3. Find PuTTY:
   • Scroll down the list of installed applications or use the search bar at the top of the "Apps & features" window.
   • Type "PuTTY" in the search bar.
   • When you find "PuTTY" in the list, click on it.
4. Uninstall PuTTY:
   • After clicking on PuTTY, you will see an "Uninstall" button. Click it.
   • A confirmation prompt may appear, asking if you're sure you want to uninstall PuTTY. Click "Uninstall" again to proceed.
   • The uninstaller will then run. Follow any on-screen prompts. In most cases, PuTTY's uninstaller is very simple and may not require further interaction.
5. Restart Your Computer (Recommended):

   While not always strictly necessary, it's a good practice to restart your computer after uninstalling any software to ensure all changes are applied correctly and any temporary files are properly cleared.

Checking for Leftover Files and Registry Entries (Advanced Users)

In some rare cases, remnants of PuTTY might be left behind, particularly configuration files or registry entries. For most users, the standard uninstall method is sufficient. However, if you want to be absolutely sure or are encountering issues, you can perform a more thorough cleanup.

1. Checking the Installation Directory

PuTTY is typically installed in the Program Files directory. You can manually check and delete this folder if it still exists.

1. Open File Explorer:
   • Press Windows Key + E on your keyboard.
2. Navigate to Program Files:
   • In File Explorer, navigate to "This PC".
   • Open the drive where Windows is installed (usually C:).
   • Open the "Program Files" folder.
3. Locate the PuTTY Folder:
   • Look for a folder named "PuTTY".
   • If you find it, right-click on the folder and select "Delete".
   • You may need administrator permission to delete the folder. Click "Yes" or "Continue" if prompted.

   Note: If you are unsure about deleting any files or folders, it's best to leave them be to avoid unintended system issues. The standard uninstall process should have removed the primary installation.

2. Checking for PuTTY Configuration Files

PuTTY saves its configuration, such as saved sessions, in a specific location. You might want to remove these if you don't plan on reinstalling PuTTY.

• Access the Registry Editor (Use with Extreme Caution):

  Editing the Windows Registry incorrectly can cause serious problems with your system. It is highly recommended to back up your registry before making any changes. If you are not comfortable with this step, skip it.

  • Press Windows Key + R to open the Run dialog box.
  • Type regedit and press Enter.
  • If prompted by User Account Control, click "Yes".
• Navigate to PuTTY's Registry Keys:

  PuTTY's configuration is typically stored under:

  HKEY_CURRENT_USER\Software\Simon Tatham\PuTTY

  • In the Registry Editor, navigate to the path above.
  • Right-click on the "PuTTY" key (folder) within the "Simon Tatham" folder.
  • Select "Delete".
  • Confirm the deletion if prompted.

  Warning: Only delete the specific "PuTTY" key. Do not delete other keys within the "Simon Tatham" folder or any other registry keys unless you are absolutely certain of their purpose and consequences.

Alternative Uninstallation Method: Using the Control Panel

The Control Panel also provides a way to uninstall programs, which is functionally very similar to the "Apps & features" settings in Windows 10.

1. Open the Control Panel:
   • Click on the Start button.
   • Type "Control Panel" and click on the result.
2. Navigate to Programs and Features:
   • Under the "Programs" category, click on "Uninstall a program".
   • If your Control Panel is set to "Large icons" or "Small icons," you will see "Programs and Features" directly. Click on it.
3. Find and Uninstall PuTTY:
   • In the list of installed programs, locate "PuTTY".
   • Right-click on PuTTY and select "Uninstall", or select PuTTY and click the "Uninstall" button at the top of the list.
   • Follow any on-screen prompts to complete the uninstallation.

FAQ: Frequently Asked Questions About Removing PuTTY

How do I uninstall PuTTY if I can't find it in Apps & features?

If you installed PuTTY as a portable application (without using the installer), it won't appear in the "Apps & features" list or Control Panel. In this case, you simply need to find the folder where you saved the PuTTY executable and delete it. Look for a folder containing the putty.exe file.

Why might PuTTY leave behind configuration files?

PuTTY's design allows it to store saved sessions and other preferences. Even after uninstalling the main program, these configuration files might remain so that if you reinstall PuTTY later, your previous settings are preserved. For most users, these leftover configuration files are harmless and take up very little space.

Is it safe to manually delete PuTTY's installation folder?

Yes, if you are certain that the folder belongs to PuTTY and you have already uninstalled the program through the standard methods, manually deleting the installation folder is generally safe. However, always exercise caution when deleting files or folders from your system.

What is the difference between uninstalling via Apps & features and the Control Panel?

In Windows 10, both "Apps & features" (found in the Settings app) and "Programs and Features" (found in the Control Panel) access the same underlying list of installed programs and use the same uninstall routines provided by the software. There is no functional difference for uninstalling PuTTY between these two methods.

By following these steps, you can effectively remove PuTTY from your Windows 10 system. Remember to always be cautious when performing system modifications and to restart your computer to ensure a clean removal.
