Missing ReactOS Functionality

This page is supposed to contain a list of APIs, Functionality, COM Interfaces, drivers, application, extensions or other that Windows has but ReactOS doesn't. There are other similar pages in this wiki that might help, e.g. Version Status, Community Funded Ideas and Roadmap. This page is intended as a list of general tasks that need to be done in ReactOS.
