Windows Update - A little bad news!

For some reason Windows Update is periodically providing as an "optional" update the following item; IdeaCom touchscreen update (PS/2). Nobody is quite sure how Windows Update has picked them for this "optional" update offer since most folks are nor even running a PS/2 on their system. The problem is that once installed this item will usually disable the touchscreen on your laptop and in the case of mice that are not installed via USB, it will also disable them. Uninstalling this is then very difficult and some registry editing may be required, otherwise it will just re-install itself and you still have the problem to contend with. To make matters worse, not all computers seem to be affected equally. My best suggestion is, if you are presented with this "optional update", do NOT install it but rather "hide" it so Windows Update will never show it again. In addition, why not Google "IdeaCom touchscreen update (PS/2)" and see how others are handling the situation. Forewarned is forearmed!
