Trust My Msix! is a Simple Command-Line App designed to import .cer files to the Trusted Root Certification Authourities Store in Windows in a few keystrokes! This speeds up the process of certificate importing for Self-Signed Msix Packages on Windows and it is very helpful to non tech-savvy users. The .msix format is AWESOME and leaves far less traces and doesn't need pressing 'Yes' a 100 times. But an .msix is allowed to be installed if the Certificate is signed by a Certificate Authourity, and getting a Certificate from a CA costs Money 💵. Normally Users have to go through the Import process of a Self-Signed Certificate which is TEDIOUS and CONFUSING, especially for Newbies. This tool makes this process take 1 second!
