Denying access for Guest in Vista

[blackrose]

I have a shared computer with Vista home premium installed on it. I wanna deny acces to Guest account to Hidden/files and folders. I am the Admin.

I was able to deny acess to Drive D: which contains my very important documents and sensitives data.

I do not want guest to change folder settings. Is there any way that I can do this. I have given Guest access to C: but I don't want them to change Folder settings and other relevent settings.

Need some built in tips and suggestions that could make this possible without installing any additional softwares.

I wanna restrict most of the functions such as editing taskbar, Right Mouse click on taskbar, access to Printer, Run, Disable Windows Key + Letter, acess to control panel, etc.
