As we can see I deleted the entry of 'Authenticated Users' and 'Users' from the security tab in C: local properties. I can still use every installed program on the PC, but unable to access C:, the message is: Denied Acess, any way to revert it?
You cannot repair the damage you've done to permissions on the C drive without a reinstall of Windows. There are too many little details that cannot be known. There are the OS default permissions which are already complex and irreproducable, and then there are the permissions set by individual applications, and finally there are likely other changes you made to permissions besides simply removing the two groups you state you removed.
The correct course of action at this point is to perform a reinstall of Windows.
