Join the Microsoft Security Essentials Ongoing Beta

Microsoft has released the final version of their security software Microsoft Security Essentials on the same day that they have released their latest operating system Windows 7.
Microsoft Security Essentials is a free antivirus software for the Windows operating system that can be downloaded and installed on PCs that pass a genuine advantage check.
Neowin today mentioned that Microsoft is currently accepting beta testers for the Microsoft Security Essentials Ongoing Beta.
Update: You can download Microsoft Security Essentials from Microsoft's website directly if you run Windows 7. This is the link. There is no ongoing beta anymore.
It seems that every Windows users with a valid Windows Live ID can join the beta test which provides access to beta versions of the security software. They need to answer a question about their operating system after log in and can then download the beta of Microsoft Security Essentials for Windows XP, Windows Vista or Windows 7.
Previous installations of Microsoft Security Essentials need to be uninstalled before the beta version can be installed. Microsoft has not released information about the changes in the available beta version. A version check reveals the following information (first final version, then beta)
Microsoft Security Essentials Version: 1.0.1611.0
Antimalware Client Version: 2.0.6212.0
Engine Version: 1.1.5302.0
Antivirus definitions: 1.71.328.0
Antispyware definitions: 1.71.328.0
Microsoft Security Essentials Version: 1.0.1743.0
Antimalware Client Version: 2.0.6212.0
Engine Version: 1.1.5302.0
Antivirus definitions: 1.71.346.0
Antispyware definitions: 1.71.346.0
The only differences are the higher program version and the definition files although those are likely shared between the public version and the beta version.
The downloaded beta of Microsoft Security Essentials will display as version 1.0.1676.0 at the beginning. The strange thing is that the Update check in the program will not raise the version to 1.0.1743.0. To get to version 1.0.1743.0 users need to click on Help > Upgrade Microsoft Security Essentials instead.
Update: Microsoft Security Essentials is still being updated regularly by Microsoft. The company has already announced plans to make the software available for their upcoming operating system Windows 8 as well.
Update 2:Â Windows Security Essentials is not available for Windows 8 or 10, but Windows Defender is. It is basically an updated version of Security Essentials that Microsoft built right into the operating system.
You can start the program by tapping on the Windows-key button on your keyboard, and typing Windows Defender.


Does it come back after every “moment” update?
Yeah right.. Like this is going to stop defender from running =) This is comedy gold right here.
no ‘about the author’ paragraph?
For permanent disable defender is if removed complete from system no just change permission folder.
Just this is joke.
simpler, load Autoruns (SysInternals)
– filter “Defender”
– untag all entries
– reboot
nothing has changed since my 1st modification years ago
I wouldn’t disable Defender imho, it has too many hidden roots inside Windows itself. One time I tried to uninstall it using brute force scripts and then the Onedrive feature stopped working definitely. A reinstallation was needed and since those times I prefer to maintain Defender untouched. It’s a better method to install another antivirus and it will disable Defender in a safer and easier mode (e.g., Avast is the best in this way, and also Panda Cloud Free is good too).
U are just * [Editor: removed] thats the problem ;p first of all u shall always debloat windows u shall have max 65 services with your drivers for pc and windows own servs. You didnt know what that script did
You can not stop defender from running in background or remove it without some penalty. All you can do is to limit telemetry.
@borts,
It’s probably Smartscreen which is preventing WD from being disabled. Get rid of that and the problem should be solved: https://thegeekpage.com/disable-windows-defender-smartscreen/#How_to_disable_the_Windows_Defender_SmartScreen_via_Local_Group_Policy_Editor
Remove Windows and go for Linux.
Linux sucks dude. Besides it’s not comparable to Windows, these OSes are in different classes entirely.
I use Linux as my daily driver. It’s far more stable than Windows. When’s the last time you used Linux, 2010?
@basingstoke
You’re right, dude. Bro, linux is just a bunch of code that starts before the OS, dude. Brobrodude, that shit ain’t even got emojis, dudebrodudeman! Dudebro, it’s no way near as cool as Windows with its hardcoded abilities to make money off the user, bro. Yo brodude man, you’re the coolest dude ever man, bro. Dude.
Lol what? Windows 7 doesn’t come with any Emojis
Download Autoruns and remove the checkmark from Windows Defender. It doesn’t remove it, but it will never run. https://learn.microsoft.com/en-us/sysinternals/downloads/autoruns
Just use “Defender Control”:

it also works on Windows 11 too…
Win Defender, is completly the most succesful free-built in antivirus of Microsoft. Really nice product. Saved my ass a lot of times. Has updated malware database, completly strong defence
from whatever smart screen disables. Or if you want better and more upgrated (paid) program,
you can go further. But defender is always on your side.
Why would one disable Windows (or Microsoft) Defender in the first place?. I consider this to be playing with fire big time. Everybody knows that if one is using another A-V, Defender will be disabled on its own and won’t be in one’s way.
Why would I want to disable Windows Defender in the first place? It’s a great anti virus in my opinion. Been using it since Windows 8 and and never had a problem or a virus. Why mess with a good thing, if it ain’t broke don’t fix it.
How a ridiculous article!
I am thoroughly stunned.
Why Should You Disable First-Party Windows Defender?
I can only think that it is “malice or perversely intention (want you to buy a third-party AV where you can expect a back margin)” to guide invalidation without showing the premise.
No sane company will use third-party closed source programs (such as AV).
As I thought, “Ghacks Technology News” seems to be coming to downfall.
