In previous versions of STAAD.Pro, the configuration file would often be overwritten. The current version you are installing adds user-writable files such as this configuration file to the user profile application data folder. Therefore, any settings changes you make will persist. The configuration file is now located at C:\Users\User.Name\AppData\Local\Bentley\Engineering\STAAD.Pro CONNECT Edition\Default\ StaadPro22.03.00.ini .
