I need users to send information about their PC, including hardware (motherboard model) and software (Windows version, including SP + .Net).
Ideally, I'd like to get this information through a web browser so they don't need to install anything. Second best would be a single EXE, ie. installer-free app, that they just need to download on their Deskop and run.
The following either use an installer or come as a ZIP file (both are too complicated for my users):
