Free Windows XP Security tool MBSA
Using Microsoft Baseline Security Analyzer (MBSA)
MBSA will help you in determining your security state. MBSA will guide you on where your system is vulnerable and give you recommendations.
MBSA is a free tool available to download from the Microsoft website. Take a look at the figures below, which will give you an idea of what the GUI looks like. I would definitely use MBSA, as it’s a fantastic tool. As you can see from the 2nd figure below, it shows me that I am missing a Service Pack for Office 2003, and if you hit the Result Details button, MBSA will show exactly what is missing and next to it will be the option to download, where you can download the missing service pack direct from here. If you haven’t already done so, download MBSA now.
