Delete games from your steam account
Click I want to permanently remove this game from my account and follow the onscreen instructions to permanently remove a game from your Steam account.
Alternately, you can open the Steam client on your PC then select a game from library while in Details view (if in Icon view, click Details). Select Support from Links column located along the right-hand side, then click I want to permanently remove this game from my account.
Steam advises that you uninstall the game you want to delete from within the Steam app before removing it from your account: If you don’t, you’ll have find the game on your hard drive and uninstall it manually. With that in mind, the first removal option is probably your best bet.
There are some catches, though: As PCGamer points out, you can’t delete bundle items you unlocked using a single product key using this method. Still, it’s a small price to pay for being able to manage your account more effectively.
