This is one of those stupid problems which wasted a lot of time before I realised what to do, so I’m sharing it here in the hope it saves someone else the grief. I recently replaced my Microsoft keyboard, but the Intellitype software was still installed. So I went into Programs and Features to uninstall it. When I clicked on Intellitype in the list of programs, the only available action was Change, no Uninstall. I then went on an internet wild goose chase, trying to find out how to uninstall. The answer was obvious – click Change and the install wizard will appear with a button to Remove. Part of me feels very stupid, but OTOH it’s pretty bad that Microsoft can’t keep own programs consistent with their own Windows standards!
