They don't come by default, apparently. Never noticed on my tablet that before. Use think link to download and install, or search them in the windows store.
WTF does "There were no games on this version of 7." mean?
Search for the game on the pc that it's on. Copy it on to a usb and copy it to the pc you want.
Or google to see if you can download it.
What he means is, on the version of Windows 8.1, you don't have all the games from the version of Windows 7.
The "WTF" you can keep it for yourself. If you don't have a good answer to his question, don't answer.
