Interacting with web pages

I have been playing around with the ie.au3 functions to learn a bit about them. I don't know anything about html, what nodes and elements are etc so will be looking at w3schools soon.

The script takes a Microsoft KB number and searches the Microsoft Update Catalog page to see if it is superseded or if it supersedes other updates. It will only work with the one supplied for now unless you change the $sDescription value.

Ideally I want to do all of this silently. There are some problems such as having popup blocker enabled and the Microsoft Catalog active x disabled in browsers so its for from perfect and do not really want to add things to peoples registry etc without consent so would like to get away from browser manipulation and would like to know if there is a com object that could be scripted to do the same as this script. I am thinking something like WSUS or  Windows Update Agent, there must be something

Looking at the source of the web pages there are lots of jscript functions? that maybe convertable to AutoIt but its above my head. I has taken me all day to get this bitty script done everything is a learning curve

I have attached the script and welcome pointers to the above and also improvements to the script
Thanks
