Can someone please tell me in simple terms now to use this tool. I saved it to desktop from the Microsoft site and it then asks you to type in a path for the files. I am at a loss as what to do at this point. I did manage to extract two files onto the desktop and I think I ran something called nospupdate. The problem was after this that I coulndnt access the Windows update site, so I restored back and then I could. I have both HP laptop and HP pavilion desktop and I have heard that HP have some problems with SP3. It seems just too much trouble with potential problems so I wish to reject the update. On my laptop it reappeared yesterday with no option to hide it as before as I believe is correct as Microsoft are now pushing the update. I definately do not want it and it is annoying to have the update icon constantly appearing which is why I wanted to run the blocker tool.
