It might be that Games are disabled from the Windows features. I would suggest you to enable it and check. Follow the steps mentioned below.
a. Click on Start and then type Programs and Features.
b. Click on Turn Windows Features on or off and then place a check mark near Games folder.
c. Click on Ok and then check whether you are able to see the games on the system.
I would suggest you to refer the article mentioned below.
