Control Console for Windows 7

I am setting up 8 stand-alone (there is no server) public access PCs with Windows 7 Home Premium 64 bit OS in our local community centre. It is a registered charity and I do the work on a volunteer basis and the charity can't afford to pay for expensive software. I need to set up each PC so that the public can use the PCs but can't make changes to them. Except for the Administrator account I wish to deny access to features like Control Panel and some other Windows options to the general public users who will use a "Standard User" accountnamed "Visitor".
Windows 7 does not provide these controls in the same way that Doug Knox's "Windows® XP Security Console" for Windows XP (Windows XP Security Console ).
A "Standard User" in Windows 7 is asked for an Administrator password to proceed with an action requiring Administrator permission whereas I want a straight "Access denied".
Is there a similar program to Doug Knox's "Windows® XP Security Console" for Windows XP written for Windows 7 Home Premium 64 bit SP1 which I can use?
Web search delivers zero hits but maybe someone out there can help.

You might do a search for an alternative to Windows SteadyState. I also think Windows SteadyState is compatible with windows 7 but is no longer supported by Microsoft.
