A mechanism for determining support criteria for shared libraries based on their priority levels is described. A method of embodiments of the invention includes extracting interface provisioning detail relating to interfaces associated with shared libraries provided by an operating system running on a computer system. The interfaces include application binary interfaces (ABIs). The method further includes detecting interface usage detail associated with the interfaces. The interface usage detail is based on a frequency at which one or more interfaces are used by one or more third-party software programs running on the operating system. The method further includes comparing the interface provisioning detail with the interface usage detail to determine an importance level of each shared library, and analyzing comparison results obtained from the comparison. The analyzing includes assigning a priority level to each shared library based on its importance level.
