HKEY_CURRENT_USER\Software\Valve\TestApp228760\SteamKey - TrackMania 2 Canyon
HKEY_CURRENT_USER\Software\Valve\TestApp229870\SteamKey - ShootMania Storm
HKEY_CURRENT_USER\Software\Valve\TestApp232910\SteamKey - TrackMania 2 Stadium
por vezes( depende como instalaram steam,o caminho pode ser diferente)
exemplo:
HKEY_CURRENT_USER\Software\
steam\TestApp232910\SteamKey - TrackMania 2 Stadium
or
HKEY_CURRENT_USER\Software\
Valve\Steam\TestApp232910\SteamKey - TrackMania 2 Stadium
neste exemplo : "TestApp232910" corresponde a trackmania stadium2, mas poderia ser outro numero , ex: " 21568" etc.
Quando não sabem a qual o numero corresponde e a qual jogo, basta ir ao google e colocar o caminho exato que encontram no regedit , nesse exemplo:
" HKEY_CURRENT_USER\Software\
steam\TestApp232910\SteamKey"
E encontram varios comentários que indicam o nome do jogo , e até o forum oficial do próprio jogo"
neste exemplo"screen" o jogo é arma 2 arrowhead (duplo clic em cima da key para ver e copiar a key )

Third party games purchased via Steam
CD Keys are issued with many third party games. In many cases, Steam will display your CD Key when you first launch your game. If your game launches and asks for a CD Key you do not have, please try the following:
1- Right-click on the game in the Library tab and select View Game CD Key. This option is not available for all Steam games and a CD Key is not required for all games.
2- Verify your GCF files. Follow the directions in the Verify Integrity of Game Cache section of the Verify Game Cache Files (GCF) article.
