Microsoft Security Essentials work with operating system Windows XP, Vista, and Windows 7. This software is designed light and do not require much storage space in computer memory. Consequently, it can be used in low specs computer, such as the netbook. Security Essentials will be able to handle a variety of viruses, spyware, rootkit and Trojan.

Microsoft Security Essentials is designed and created to find and kill the evil and malicious programs that can steal passwords or change the computer as a spam distributor.

The software will download the latest collection program evil day after day. It will appear as silent, except when it detected a threat from dangerous software. Microsoft is also designing a database on the source software that can be trusted. So, the Security Essentials will not block the browser toolbar from Google Inc. for example.

This implementation is as close to a “disc in the drive” experience as possible over the Internet. At a high-level, here is how it works:

* Video startup is nearly instantaneous because of the back-end proprietary Microsoft technology developed by Zune that seamlessly transitions between many different bitrates and resolutions of video.
* Video playback will start at a low bitrate for fast download time and then ramp up to a higher bitrate and quality, up to 1080p with 5.1 audio.
* Features such as smooth fast forward and rewind that users have only seen before with local physical media.
