If you are here because you want to fix a game problem, stop what you are doing and validate it. Validation does everything uninstalling does (except change your settings, which doesn't require reinstalling either) in a fraction of the time and with a fraction of the bandwidth.

If that doesn't apply then here is how to perform a proper, clean reinstall of Steam:

  1. Write down your Steam Account name and password - you will need them to log back into Steam once you have reinstalled
  2. Logout of Steam if you are able to do so
  3. Exit Steam
  4. Move SteamApps out of the Steam folder. This is the folder that holds your games so you want to keep it!
  5. If you are having problems with a specific game, delete it's folder from SteamApps/<account> - Uninstall via Add/Remove programs, if you can
  6. Restart if prompted
  7. Delete Steam folder if it still exists
  8. Hit windows key + r and type regedit
  10. Restart
  11. Download and install a fresh copy of the Steam installer from
  12. Run the installer
  13. Exit Steam before you first login
  14. Move your SteamApps folder back
