PowerShell – Get latest Microsoft KB information

I frequently visit kbupdate.info which is a great resource for finding latest KB updates, but still you have to manually click through the various lists. Now that I am learning PowerShell anyway, i thought i’ll give myself another task to further improve my PowerShell skills. So here we go, below you find a script that retrieves the latest KB update information for various products and displays them on screen so that I can quickly browse through them and directly launch the article of interest in Internet Explorer.
