Security+5e Lab15-1: Using Secunia Personal Software Inspector (PSI)
The current version of PSI contains several advanced features. It supports applications from more than 3000 different software vendors and encapsulates all of the vendor patches for your computer into one proprietary installer. This installer suppresses any required dialogs so everything can be patched silently without any user intervention. You can even create rules, such as telling PSI to ignore patching a specific application.
