Hi TahaZahid
I am Dave, I will help you with this.
If you have randomly deleted files form the Common Files folder, and emptied the recycle bin, then those files will not be recoverable, and there is no way to known what applications or games will be affected by deleting those files and a system restore would not restore those files.
The only thing you can do is, when you find an app or game that is not working as expected, re-install it.
