Hiding system folders on a shared computer

[apertotes]

Hello, I am sharing a computer with my son and I want to hide some programs from him, mainly Steam games, but not only. I have managed to hide them from his start menu. He has a standard account, so I think on that front we are OK.

I have also managed to prevent him from accessing the control panel, and thus seeing the list of installed programs.

But I have a problem:

Windows explorer. I tried navigating from his account, and he can go into program files without any problem, he can even go into windows folder. He can not delete files, but he can run them. So, you know how kids are. He will see all the installed programs and try to run directly their .exe file. And even though he won't be able to launch Steam games, he will see a list of all installed games, and I want to prevent that from happening.

He can even go to "Start", type "witch" and a few seconds later he'll be able to see that we have The Witcher 2 installed on the computer. He won't be able to launch it if I activate Parental Controls, but the damage is done.

So, can anybody help me hiding certain folders (windows and program files) from a standard user explorer?

Thanks!

Can you set a Deny Execute ACL for his user on the game's directory under Program Files?

I could... if I knew what that meant 🙁 Would you elaborate, please?
