How should I uninstall Steam?

Important:

This process will remove Steam and any installed game content from your machine. If reinstalling Steam and Steam games in the near future, please move the steamapps folder (C:\Program Files (x86)\Steam\steamapps) outside of the Steam directory to prevent your games from being deleted. Additionally, backups of all game content can be created for reinstallation.

Warning:

The uninstallation process deletes the folder Steam was installed to to ensure it is fully uninstalled. If you accidentally installed Steam to a folder containing other data, for example C:\Program Files (x86)\ instead of C:\Program Files (x86)\Steam\

STOP! Do not run the uninstaller and instead carefully follow the instructions below for Manually Removing Steam, except only delete Steam-related files in step 3.

Please observe the following procedure to uninstall Steam and any game content from your machine:

Note: The following instructions are for Windows 10. For older versions of Windows please see Microsoft's support site for instructions on how to remove an application for your specific version.
  1. Exit Steam
  2. To keep game installations, move the steamapps folder out of C:\Program Files (x86)\Steam
  3. Click the Windows Start button and select the gear icon for the Settings
  4. Select Apps from the Settings window
  5. Search and click the Steam entry from the list and then click the Uninstall button that appears
  6. Select the Automatic option and click Next
  7. Click Finish to uninstall Steam


If the normal process to uninstall Steam does not work, you may have inadvertently damaged your Steam installation. To uninstall Steam, you may first be required to re-install Steam to repair the installation before it may be removed.

The latest Steam installer can be found on the Get Steam Now page.

If all of the above options fail to assist you in uninstalling Steam, you can still remove your Steam files and registry entries manually.

For Mac OS uninstall instructions, please see the Removing and Reinstalling Steam on a Mac page.
