    Windows Defender manual update

    Initially on Win7, I was manually updating Security Essentials when was offline from this link:

    How to manually download the latest definition updates for Microsoft Security Essentials

    You choose x86 or x64 and go from there.

    What's not mentioned, is that you can use the same links to update Windows Defender on Win8 as well.

    I've been doing this for quite some time without issues. So the two programs are very much alike.

    Why do you need to manual update offline ? I can manually update online anytime by opening Windows Defender, click on update tab then click update. What is the difference ?

    The difference?
    EDIT: it's good you've asked. This wasn't explained in the initial post. Thanks.

    I have NO INTERNET on the pc in question (at least not permanently). Other pc's are online and the modem is all used up. I could add a cable connection (regularly updates) to this one... but no big deal because the current setup suits the needs.

    So this might be a weird setup (but it works) for you nowadays but when you're offline, a week or so, the virus definitions pops up saying is out of date.

    That's why the website link I provided exists because not all pc's are online. You simply run the setup moved on USB to the offline PC and run it. Then the AV/spyware engines get updated.

    Another usage to this: If you're infected by some serious malicious software, you should definitely go offline if possible to solve the problem (online connection might make the malware more resistant to cleaning operations).

    It' just a nice possibility to be able to update antivirus engines offline and this method is provided by many AV software companies/products.

    That's all.
