Remarks

Exception packages are Windows system files that are released outside of a full package Windows release and that update operating-system files. Exception packages are authored only by operating-system teams that have been granted authorization to update Windows system files.

To install and uninstall files that are not protected by Windows File Protection, use the functions documented in General Setup Functions. To install device drivers, venders should use functions documented in Device Installation Functions and PnP Configuration Manager Functions.

This function has no associated import library or header file; you must call it by using the LoadLibrary and GetProcAddress functions.
