Yes, the Microsoft Fixit is an application that can be started for free on Windows installations that have issues with various Windows components. Unfortunately, the Fixit page/tool doesn't appear to be available anymore or, if it is, the tool is placed on various knowledge base topics.
If you know the error in your computer, search it on Google and add the fixit word to the search term. If there is a Fixit version, it will be available for downloading on the support page.
