Windows XP is deemed ‘good enough’ by many, but the fact is that it’s four to five times more vulnerable to malware infection than Windows 7. While this is mainly due to improved security defenses, including least privilege security implemented with the help of User Account Control (UAC), that’s not to say we should be complacent when using Windows 7.

Privilege Guard (Edit: now Defendpoint) first introduced UAC (User Account Control) integration in version 2.5, which enables rules to be defined that trigger when an application requires administrator privileges in order to run. Further enhancements to the UAC rule in version 2.7 now allow you to elevate applications that may trigger UAC after the application has already launched. For instance, disk defragmenter and task manager are two applications that launch with standard user rights and only trigger UAC when the user attempts to perform an operation that requires administrator privileges.

One of the most common reasons cited for granting administrative privileges to notebook users on Windows is the need to install drivers for new hardware when IT support isn’t available. Happily, Windows 7 has improved driver handling and it’s likely that when a new device is connected, it will either be supported out-of-the-box, i.e. a driver for the device is included with Windows 7, or a driver will be automatically downloaded from Windows Update and pre-staged into the driver store (c:windowssystem32driverstore) so it can be installed by a standard user.
