You really can't do that. The games will have to be reinstalled.
There is something called Windows Registry. One of the things it allows Windows to know what programs are install on the PC / laptop. That is done during the installation process; as the program or game is being installed it makes changes to the Windows Registry. It allows the game to access various files within Windows in order to run such as DLLs (dynamic linked libraries) that are related DirectX.
For example, if you have Fallout 4 installed on your current laptop and you simply copy the directory to your new laptop, the game will absolutely not run.
