    Microsoft Download Center page – via your link above – shows the download for MSE version 1 but the publish date is given as 16-Dec-2010. Uh?

      The download link should provide the download for MSE 2.0. While the title of the page reads “Microsoft Security Essentials”, it is actually MSE 2.0.

    Wow, the UI of MSE 2 looks exactly like the newly released Forefront Endpoint Protection 2010 client. It was to be expected, as both products are based on the same engine, but it looks like the only difference is the “MSE” / “FEP” moniker in the title bar.

    Impressive, and very unlike McAfee. :-)

      The title bar and the manageability features. Windows 98 and 2000 had similar UI too but were totally different under the hood. :)

    I’ve just installed it, and it’s great. Way better than AVG Free 2011, or even AVG Internet Security 2011 (which you have to pay for). It would be better if it came through Windows Update, though, because not everyone reades LiveSide.net (why not??) and would know when a new version came out.

      Glad you’ve discovered the beauty that is MSE! I’m with Paul Thurrott: just bundle MSE with Windows. It’s inexcusable not to, and if users want even more protection and bloated software, they can find Norton or McAfee or whatever AV solution they prefer. I don’t think there would be any anti-trust issues as security is a main–and arguably most important–aspect of any quality operating system.

        Definitely.

    No wonder; I was installing MSE on a computer last night and noticed the gray theme from the Beta. I really don’t know why people still put up with AVG Free and its clunky UI.

      AVG 2011 does have a new UI – but it’s black and stuck that way. AVG are always saying how basic AVG Free is, and how you should upgrade to the paid version (they bhave ads in the free version). AVG Free really isn’t that good – I used it for a while then switched to the easy-to-use yet powerful Microsoft Security Essentials. Oh I do wish the upgrade to version 2.0 came through Windows Update as an ‘Important Update’. In fact, Windows Live Essentials should be an Important Update. And Windows Live Essentials 2009 should no longer be in Windows Update (one of my computers didn’t have WLE and WLE 2009 came through Windows Update as an optional update – this was in November).

    I’m glad they chose to stick with a dark gray theme this time. I’m getting a bit sick of these washed out themes.

    Though the cartoon-ish theme from the early days of MSE (when it was under that other name) was pathetic and reminded me of how XP was cartoon-ish

    That it is a big step but we must do more important steps if we want to be total securized.
