Microsoft Security Essentials Beta Opens for Public

Microsoft has made the beta for the new version of Microsoft Security Essentials (MSE) available for public widely. Earlier, the beta was only available for a limited number of beta testers.

The download isn’t straightforward though. You need to click the Download Now link on the Microsoft Security Essentials homepage that would take you the MSE beta page on Microsoft Connect (Windows Live ID required). The current beta build is version 4.0.1111.0. The beta is available both as 32-bit edition (8.87 MB) and 64-bit edition (11.04 MB). The software supports Windows XP with Service Pack 3, Windows Vista with Service Pack 1 or 2, and Windows 7 with Service Pack 1.


This latest version includes the following new features and enhancements to better help protect your PC:

  • Cleans highly impacting malware infections automatically, with no required user interaction
  • Enhanced performance
  • Simplified UI
  • New and improved protection engine

While, Microsoft Connect is used to engage with beta testers by encouraging participation in surveys to report results or submitting bugs, the MSE Beta page doesn’t have those available at this moment though.
