Why Must I Do This? When you use “change user /install” before installing an application, you actually create .ini files for the application in the system directory. These files are used as master copies for user-specific .ini files. After installing the application, when you type “change user /execute” you are reverting to standard .ini file mapping. The first time you run the application, it searches the home directory for its .ini files. If the .ini files are not found in the home directory, but are found in the system directory, Terminal Services copies the .ini files to the home directory, ensuring that each user has a unique copy of the application .ini files. Each user should have a unique copy of the .ini files for an application. This prevents instances where different users might have incompatible application configurations.
