How to detect and update vulnerable and end-of-life programs using Secunia PSI in Windows XP, Vista, 7, 8 and 8.1

While Windows Update keeps most of Microsoft's software up-to-date and patched, many other vendors do not have very good automatic updating capabilities for their programs. This means that, for example, unpatched versions of Java Runtime Environment or Adobe Flash Player might leave your Windows computer open to attacks from the Internet.

Luckily, there is a good solution for it - Secunia's Personal Software Inspector (PSI, for short). This really cool and free program from Denmark scans for vulnerabilities in Microsoft and non-Microsoft software and is able to patch most well-known programs automatically.
Version 3 of PSI is much simplified to avoid user confusion, yet smart enough not to whine about unnecessary items (such as program installers and programs not in use by Windows) anymore.

You can always see if your computer is up-to-date by checking PSI icon in Taskbar Notification Area - if the icon is green, everything is ok; yellow/orange means that a few programs are unpatched or out of date; red means that attention and manual update is required.

To open Secunia PSI, right-click its icon in Taskbar Notification Area (aka System Tray) and click Open Secunia PSI. Please note that clicking or double-clicking the icon has no effect. In Windows Vista, 7, 8 and 8.1 this will wake the most beloved User Account Control, so click Continue or Yes.

Configuring Secunia PSI

Since version 3 of PSI, settings have been drastically simplified to enhance user experience. The Settings button in the bottom of PSI window has just four options:

  • Detailed view - this is meant for specialists who need more details on program versions and criticality levels.
  • Start on boot - this makes Secunia PSI run automatically in the background after Windows starts. Keep this one turned on to enable automatic scans.
  • Update handling - keep the Update (recommended) option checked to patch and update programs automatically.
  • Scan individual drives - system drive (the one where Windows is installed) is always scanned automatically. If you have a separate drive or partition for programs, stop mouse pointer on the option for a while until a list of drives appears (this might take several seconds). Then enable or disable the scanning of additional drives. Please note that this list includes hard drives only, removable drives are not shown here.

Secunia PSI 3, Settings, Update handling. Leave the 'Update (recommended)' option selected. Secunia PSI 3, Settings, Scan individual drives. If programs are installed on other drives than system drive C:, select these here.
