Requirement (Designed for Microsoft® Windows® Logo)
Your application must not add information to Win.ini or System.ini.
Applications that must support links to existing 16-bit products can write to these files. For example, certain multimedia applications may require video codecs not supplied with Windows NT or Windows 95. Certain other products, such as screen savers, may not be supported in the registry and must write to Win.ini or System.ini. Writes to the embedded section of Win.ini may be unavoidable. It is okay to write to the font section of Win.ini and to leave behind fonts and font information after uninstallation. However, any writes to Win.ini or System.ini must be explained in the Vendor Questionnaire.
