Why this RDCMan site does not mirror the executable
A local mirror would insert an independent website between the software publisher and the administrator. The master goal for this site is a clear, legitimate route to Microsoft, so the call to action stays external and visibly labeled.
No website should replace your normal file-validation, endpoint-protection, application-control, code-signing, or change-management process with a “100% safe” promise.
