Microsoft Standard User Analyzer

Overview
The Standard User Analyzer helps developers and IT professionals diagnose issues that would prevent a program from running properly without administrator privileges. On Windows Vista, even administrators run most programs with standard user privileges by default, so it is important to ensure that your application does not have administrator access as a dependency.

Using the Standard User Analyzer to test your application can identify the following administrator dependencies and return the results in a graphical interface:

? File access
? Registry access
? INI files
? Token issues
? Security privileges
? Name space issues
? Other issues
