If you’ve completed a Steam game, or if you’re just tired of playing it, you can uninstall it from your PC to regain some of that valuable storage space. You can uninstall a Steam game using the Steam client or through Windows, the same way you would uninstall any other app.
Uninstall a Steam game using the Steam client
To uninstall a game using your Steam client, launch the Steam client and then click the Library tab in the top-left corner of the window.

Next, locate the game that you would like to uninstall in the left-hand pane. Games that are currently installed will have bright white text, whereas the games that aren’t currently installed will have grayish text.
Right-click the game’s title from the list. A context menu will appear. Hover your cursor over Manage and then click Uninstall in the sub-menu. Note that you can select multiple games to uninstall by holding the Ctrl key and selecting the games. This allows you to uninstall games in batches.
