I have an app that writes a temp file to the root of the C drive. If I am not mistaken Windows 7 & Vista has access to the root of C: virtualized, so modifying user rights does nothing at the root. I am wondering if anyone had any success making changes to the user right using Microsoft Application Compatibility Toolkit 5.6? Thanks
