MiCOM S1 Studio is a program for programming MiCOM (Alstom\Schneider) power system protection relays. For unknown reasons, sometimes the program will enable the password setting seemingly by itself, which can essentially lock all access to the program. This program will reset the password.
To use, simply run the program, and it will attempt to detect S1 Studio installations on your system.
Follow the prompts to either reset the password automatically, or just print the new password hash to screen. This hash should be copied into the Configuration.bin file, which normally resides in C:\ProgramData\Schneider Electric\MiCOM S1 Studio\<version>\.
Note that the program must be run on the target machine to generate the correct hash.
