Hi
is there a way to update only windows defender via windows 11 update , maybe with a 3rd party free software

for update ,i don't mean windows defender signature but the windows defender software

or to keep windows defender should i update everthing on windows 11

thanks

Aside from from signature updates which MS pushes as they become available throughout the day, Defender receives platform and engine updates each month automatically. No user interaction is required. Of course, at any time you may right-click on the tray icon to trigger signature updates manually.

As a Windows Pro user, you may choose to receive Beta platform and engine updates via GPO or by using powershell. You can get more info on all Defender intelligence updates at the link below.

Hi @oldschool
i mean , sometime i 'm used to stop the windows 11 updates , i don't want to update everthing , if i can i would like to perform a "custom" update ,not everythign , just to avoid iuesses

I would like to update and keep update windows defender (the program , the antivirus ) , about the signature i can update manually
can I update only windows denfender "the program" ? or is it part of windows 11 22H2 or 23H2 ?
sorry for my bad english
thanks

Windows Defender consists of three components:
- Defender platform (engine and background services)
- Defender signatures
- Security Center (or SecHealthUI app)

Each of them can be downloaded separately from MS sources. Platform updates are provided once a month, Signatures are provided every day, and SecHealthUI is harder to track down.

If your goal is to block normal Windows Updates, but continue to receive Defender updates, the normal solution is to pause WU indefinitely.

hi
in your signature i can read "Block unknowns | ASR rules "
can i know how can i block unknowns ?
and is there a "ASR rules" rules just to teach me how to use and create them?
thanks

There is no freeware to download Defender files. Because why? MS only guarantees Defender security when you allow it to do its own job.

For reference, here are the download links. But you're responsible for installing them.

Platform:

Definitions:

SecHealthUI:

If you want direct downloads, steven4554 runs a Defender Platform thread on another site. Out of respect for Brink, I won't cross-post it but it's easy to Google.

The max or highest setting is Defender's most aggressive one. It blocks all unknown executables. Attack Surface Reduction (ASR) rules can be enabled individually as users wish. Choosing the Max setting in ConfigureDefender will enable all of the above. There is a log to check for blocked events. If you find that some of your needed applications are blocked you may add exclusions where applicable or disable the offending ASR rule if it doesn't allow exclusions. All of this can be accomplished through the CD app. For more info or questions about ConfigureDefender please see ConfigureDefender

BTW, just a reminder that you don't need to manually download and install any Defender updates as @Garlin suggests. You receive them automatically.

I don't think he understands if you pause WU, Defender updates keep coming but no other Updates are provided. Or that Defender is designed to be a continuous service.
