Intel's latest drivers for HD4400 offer an ability for you to force a version of "post processing" AA called CMAA on through the Control Panel...
See info in the release notes from when this feature was enabled:
CMAA* (Conservative Morphological Anti-Aliasing)
The driver includes CMAA* (Conservative Morphological Anti-Aliasing) for DirectX, a post-processing effect in games that reduces the jagged edges during gaming.
Benefits and utilization:
CMAA offers higher quality anti-aliasing effect than MLAA (Multi-sample Anti-Aliasing)*, FXAA (Fast Approximate AntiAliasing)* and without performance impact. See this white paper for more information.
This effect can be initiated through Intel Graphics control panel.
Enable the feature via Intel Graphics control panel before launching a game and disable after game is exited to avoid
any unintended blurring in other applications.
To reduce the probability of unintended blurring, certain applications are automatically excluded from the support
list: Windows* explorer, login screen, Windows* home screen, Internet Explorer*, Google* Chrome, and Firefox*
browsers, and the Windows 8.1 Photo applications
