    Add or Remove Windows Defender Exclusions in Windows 10


    @Brink - Shawn, this is a good one to know, and I would add one thing. The "Why would I want to do this?".

    Files and folders (including whole external drives or partitions, etc.) may be obvious, but excluding a process may not be.

    The process you chose for this tutorial (MBAM) is a perfect example. Malwarebytes scanner is a well used and trusted anti-malware product. I cut the run time of a full scan using MBAM w/Def exclusion by about 50%... 18 mins to 9 mins. Windows Defender did did not have to monitor a trusted process. This can be seen by running Task Manager and monitoring the MsMpEng.exe.

    It would be wise to point out, though, to not take this option too far! Only use it in cases where you are comfortable and know the risk level is extremely low. Example: DO NOT add Spartan.exe as an exclusion!

    Thanks for the Tut!

    :)

    Would anyone know if path exclusion is recursive? Also is there a way to specify wildcards?

    Hello Biatche, *Smile

    If you exclude a "File location", then WD will exclude all files and subfolders on that location.

    I don't believe you can use wildcards, but if you add a "File type" exclusion, then all file types with that extension will be excluded.

    Hello Brink,

    I was wondering if you can help me please.

    I have selected certain file types / folders and locations in Windows Defender on Windows 10 that were added to the exclusions lists...

    Previously I could go to Windows Defender and see what files, folders or extensions I had excluded but now they have disappeared....

    All I see is the add buttons which work as intended when I want to add a folder etc etc....
    But then they are not listed anywhere so that I can remember what I have excluded or not....

    Can some one please help me so that they are visible again, is there a setting in the registry that needs to be fixed?

    This is what I should see where, below the red arrows I should see the excluded files/folders including their path etc etc [see image below]

    Add or Remove Windows Defender Exclusions in Windows 10 [​IMG]

    but I see nothing..

    Yet if i go to the registry as indicated below...

    File and file location exclusions are stored in the registry key below.

    *Arrow HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender\Exclusions\Paths

    File type exclusions are stored in the registry key below.

    *Arrow HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender\Exclusions\Extensions

    Processes exclusions are stored in the registry key below.

    *Arrow HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender\Exclusions\Processes

    they are all listed there....?

    I have to say that windows defender is excluding folders/files and etc etc, that I have selected during its scans, but I cant see the excluded items in the Windows Defender as per image of my Exclusions section below...

    Hello Kokakola, *Smile

    The only way that I know of to add them back is to delete them in the registry, and manually add the exceptions back in Settings.

    I'd recommend to export the Exclusions key first to be able to use it as a reference to help add all of the exceptions back.

    Hhello BRINK,

    I have already done that in the registry and re entered them again but they still refuse to show up in the section under exclusions... is it that the settings in the registry are set wrong?

    mine all have value not set? is this the issue...

    Just to verify, you re-entered them in Settings and not from the registry?

    Go ahead and restart the computer, and see if you are able to enter them in Settings and have them show.

    Please aslo post a screenshot showing what you see in Settings to see if it may reveal anything.

    I have done as you advised but still no go...

    as you can see from the images attached i see the exclusions listed in the registry but they wont show up on windows defender...

    has it anything to do with the fact that the registry values are not set?
    as shown in the images attached...
    thanks in advance...

    I'm not sure what you mean by the registry values no being set. It's shown as set in your first screenshot.

    Just to verify, did you delete the Path key in the registry? Usually, you'll have to change the owner of the key to "Administrators", and "allow" Administrators "Full control" of the key first, then delete it.

    If so, then I'm not sure why they are not being shown in Settings when you added them from Settings.

    No I did not delete the "Path" key from the registry I just deleted the contents within the "Path" key...

    I'll try deleting the "Path" key now and reset and see what happens.....

    **EDIT**
    Fixed... deleting the "Path" key in the registry as you advised and then resetting the PC brings them back...

    thank you so much....

    cheers

    Hi Shawn,
    just upgraded Windows to OS build 10586.3 & was attempting to install MBAM alongside Defender & set up the exclusions. I don't see an option to browse to the process that I would like to exclude as before - in Defender.
    I can enter the fully qualified path name e.g. C:\Program Files (x86)\Malwarebytes Anti-Malware\mbam.exe but it seems the option to browse the directories should still be there.
    Am I missing something?

    thanks,
    richie

    Are you using step 4 in OPTION ONE to "Exclude a file" under "Files and folders"?
