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.
