Note: These logins have every Steam game unlocked and are updated pretty regularly.
You need to have .NET 2.0 installed, as well as VB6 runtimes.
Download --> https://************/?id=b17d1d (Cracked Steam Cafe)
First thing you need to do is edit your registry.
Start > Run > regedit
Expand HKEY_CURRENT_USER
Expand SOFTWARE
Expand VALVE
Click on STEAM
Right click right panel, New > DWORD Value
Name the value "CybercafeSSA", no quotes.
Right click CybercafeSSA and modify
Change the value data to 1 and hit OK.
Now, install the program you downloaded above. Part of it's in German, doesn't matter. Once it's installed, run the Cracked Steam Cafe .exe. It'll open up the Steam login shell and another program with a list of logins. Close the Steam login screen and select one of the logins, doesn't matter which one. The master password is "Eddy K". Just enter that into the text box labeled master password, then double-click on any of the logins.
Voila, you're logged in. All the games are unlocked and fully downloadable. As far as I can tell, the CSC file just grabs some random logins from a central server and gives them to you. I haven't yet been booted from someone logging onto the same one I'm on, but I've heard that this may happen.
