Microsoft’s Enhanced Mitigation Experience Toolkit (EMET) is free software that improves the overall security of Windows computers. EMET isn’t a replacement for anti-malware software; rather, it provides additional protections that complement anti-malware software.

There’s little downside to using EMET, so we recommend installing it on all Windows computers. By default, it provides specific protections for Microsoft software, including Office and Internet Explorer.

Version 5 adds new mitigations and features.
