MSAA is the Microsoft Active Accessibility API used on the Windows operating systems to provide helpful functions for users with disabilities. Microsoft Active Accessibility is a COM-based technology developed to improve the way accessibility aids work with programs running on Windows. The oleacc.dll is a dynamic link library which supports functions for Microsoft Active Accessibility.

Accessibility aids may include screen readers for the visually impaired, visual indicators or captions for people with hearing loss, and software to compensate for motion disabilities. Active Accessibility incorporated the DLL oleacc.dll into the operating system as well as to the COM interface and other application programming interfaces that grant reliable methods for exposing information about user interface elements.

Since Windows 98 and Windows NT 4.0 Service Pack 4 the oleacc.dll module compliments MACC that has been built-into all versions of the Windows platform. Microsoft since then has maintained periodic upgrades over time to increase its robustness and efficiency.

In addition to the Microsoft Active Accessibility a new managed code accessibility Application Programming Interface known as Microsoft UI Automation (UIA) is being introduced with .NET Framework 3.0 to drive user interfaces.

What is a DLL?

DLL (Dynamic Link Library) files contain computer code and resources that can be used by multiple programs at the same time. This uses less system memory and helps your computer system run more efficiently. DLL files give program developers the ability to reuse code to add features to several programs without the need to write new code for each program.

There are many programs that require DLL files to function properly so when one of them is damaged or missing it will cause program crashes and poor system performance.
