How To Update Microsoft Security Essentials (MSE) Offline
Posted September 30, 2009 – 11:17 am in: Windows 7 TweaksIf you have already installed Microsoft Security Essentials final on one of your Windows machines that has no internet connection and looking for a way to update the virus definition updates, here is a quick and easy solution.
Although Microsoft clearly states on the Microsoft Security Essentials system requirements page that an Internet connection is required for installation and to download the latest virus and spyware definitions, you can still update the MSE offline. Of course, you need a computer with Internet connection to download the offline updates!
Once you install MSE on a machine, it will try to update the virus and spyware definition. If the machine is not connected to the Internet, it will display “Microsoft Security Essentials wasn’t able to complete the virus and spyware definition updates. Make sure your computer is connected to the Internet and try again” error.
How to update Microsoft Security Essentials Offline:
1. First you must know whether Windows XP, Windows Vista, or Windows 7 is running in a 32-bit or a 64-bit operating environment. You can find it easily by opening system properties (use Windows + Pause/Break key to open system properties).
2. Next, download the offline definition updates for MSE from Microsoft:
Just save the file on a USB stick so that you can connect the USB stick to the offline machine and then update MSE.
3. If you are on Windows 7/Vista, right-click on the downloaded file and select Run as administrator. If you are prompted for an administrator password or for confirmation, type the password or click Continue. And if you are on XP, simply, double-click on the file and click Ok.
4. You will see file extraction dialog box for a while. After the file extraction dialog box closes, open MSE, and click Update to verify that the virus and spyware definitions have been updated.
5. You are done!

Thank you so much for this!
Do you know if Microsoft provides those offline updates daily?
I’ve been itching to test this out on my XP Desktop, which is my only Windows machine
@ Chris
Sadly, it’s not available on daily basis.
Did you have an link to an orginal microsoft article for this offline update feature?
thank you
You can’t install MSE without internet connection.. (remember it has to validate the windows!) and if you want to re-install the MSE then it is better to use the offline updates… ( and the pack contains most updates*)
there is no problem if you downloaded them daily.. but it looks like waste of time..
*pack contains the past updates also.. when you live update them they will download a CURRENT updates..
any dobt mail me.. help@goodkeys.co.cc
bt u can’t run scan till Security Essentials updates.
Extraction failed
File is corrupt.
Great work , I have a friend who does not have internet so i’ll just download the files for him
I tried to get offline updates for other av’s but did not find
Q: will this work if the program is a clean install , because you must update to run MSE ?
great!!! this really helps for offline computers who need virus protection and need to be updated
