Microsoft’s Morro is creating a buzz everywhere since a long. I have also posted Microsoft Morro screenshots last day as it got leaked on internet. And now finally Microsoft Security Essentials (MSE) also got leaked on internet and you can try your hands on this new Microsoft product by downloading it for free. Microsoft was using the codename Morro for this antivirus, but finally it got a official name and it’s Microsoft Security Essentials (MSE) now. Microsoft Security Essentials is coming to replace previous Microsoft releases such as Windows Live OneCare and Windows Defender.

MSE is Microsoft’s free antivirus and windows security program that comes for free and hence you can’t expect some additional features like Firewall, Email scan and protection etc. Commercial antivirus programs like Norton, Kaspersky, AVG will work much better than this free product, but if you are not much into web browsing and do it once in a while, Microsoft Security Essentials will work fine for you with it’s dedicated protection level against virus, spywares, malwares, adwares etc.

Microsoft is planning to allow people to download MSE beta version in September while the original and full version of Microsoft Security Essentials will be made available later this year. If you want to try your hands on this new security product from Microsoft, you can download MSE now. However, since this leaked version is the pre beta release, you may find several bugs and limitations. This leaked version is named as Microsoft Security Essentials (MSE) 1.0.2140.0.

This leaked version has been tested and worked on since June 1 this year. This supports operating systems like Windows XP, Windows Vista, Windows 7 etc. Since this is the leaked version, virus signature database auto update can’t be assured. You have to download this as a standalone Microsoft Security Essentials (MSE) software download.

Download Microsoft Security Essentials (MSE)

Download Microsoft Security Essentials (MSE) for 32-bit (x86) Windows Vista and Windows 7

Download Microsoft Security Essentials (MSE) for 64-bit (x64) Windows Vista and Windows 7

Download Microsoft Security Essentials (MSE) for Windows XP

The only problem with Windows Security Essentials installation is it requires WGA activation. If you have not validated your Windows copy using WGA procedure, MSE won’t work on your computer. So, you must validate your Windows copy in order to make MSE work.
