CompTIA Security+ SY0-701 Practice Question

Applying updates, or 'patching', is essential because it resolves vulnerabilities that could be exploited by threat actors. Ignoring updates leaves systems susceptible to attacks that target these known weaknesses. Other options such as 'increasing system performance' or 'enhancing user interface' might be secondary benefits of some updates but are not the primary security purpose. 'Expanding compatibility' is usually not related to the security aspect of patching.
