Intel Driver & Support Assistant keeps failing to install updates

Laptops are the usual case for this. HP, Dell, Lenovo and the rest ship their own customised version of the Intel graphics driver, and the generic one from Intel often refuses to install over it, or gives a warning that it isn't validated for your computer. It's safe to ignore. Get graphics drivers from your laptop maker's support page or Windows Update instead. You can uninstall the Intel assistant if the nagging bothers you. Only force the generic driver if you need a specific fix the maker's version doesn't have yet.
