I've just received the following "optional" update through Microsoft Update system.
Microsoft - Other hardware - Microsoft Hardware USB Keyboard Download size: 174 KB
You may need to restart your computer for this update to take effect.
Update type: Optional
Microsoft Other hardware software update released in December, 2010
Help and Support:
However, when I install it, every time I restart the PC, it tries to "install" the Microsoft Ergonomic Keyboard 4000 drivers. Usually, PC remembers the installation and you do not have to re-install the driver every time you unplug the keyboard or restart the PC. This update, for some reason, forces the PC to install the drivers and download the "keyboard" configuration ever time you restart or unplug/replug the keyboard. Reinstalling Intellipoint does not work! Its pretty annoying this installing thing.
In the end, I just did a system restore to the point BEFORE the update and hid this update.
Edit: Apparently this update has been pulled by Microsoft. It no longer appears in the hidden update.
I found out that the release of the driver update is coupled with the release of a new version of IntelliType, Microsoft's software to customize your keyboard. The software ALREADY include the driver that Windows Update wants to update. Go to http://www.microsoft.com/hardware/en-us/downloads and chose the Microsoft hardware product you have. Then chose the operating system that you have (make sure to correctly identifying whether your PC is 64 bit or 32). After download the IntelliType sofware and installing it. After installing the new version of IntelliType, the update will go away.
