  1. Windows Defender Block Access


    Every time I try to download something, my Windows defender blocks everything, it gives me the following message: Unauthorized changes blocked, Controlled folder access blocked with C:\... then the rest of the extension but it doesn't give me the full extension so it is very hard to find the location of the file to add it to my exceptions? Is there a way I can remove that blocking option because it is very annoying or at least see the full extension of where the file is located.


    Thank you,


    [Original Title: Windows Defender]

    Windows Defender is blocking too much saying it viruses

    Hi Sam,

    Based on the screenshot that you've provided, Controlled Folder Access is turned on, blocking most apps that you're using. We suggest that you turn it off to allow blocked apps in Windows Defender. Follow the steps below:

    • Select Start > Settings.
    • Choose Update & security > Windows Defender.
    • Select Open Windows Defender Security Center.
    • Select Virus & threat protection, and then choose Virus & threat protection settings.
    • Under Controlled folder access, turn it on or off.
    • Once done, try accessing the apps and see if you can now access them.

    Should you need further assistance, feel free to post back.

    Turn On Windows Defender Block Suspicious Behaviors in Windows 10


    The DWORD is set to 0 and I cannot get the process you suggested in the "NOTE" portion of the tutorial to work. Two attached screen shoots will show the before and after attempts to change the Permissions necessary for access to the DWORD change.

    Windows Defender Blocking

    Hi Aeolus0,



    You can add allowed folder or apps in the Windows Defender Controlled Folder Access, as it basically blocks almost every changes when it is turn on. You may try to follow these steps to add allowed apps:

    • Open Windows Defender Security Center then select Virus & threat protection icon.
    • Click the Virus & threat protection settings.
    • Click Allow an app through Controlled folder access.
    • Select Add an allowed app, navigate and select the app you want to add, select Open then click Yes.
    • You might be prompted a UAC to continue.
    • You can click the Remove button if you want to remove the added app.
    • Close the Windows Defender windows.


    On the other hand, if you want to allow a blocked app in Windows Defender Security Center, you may check this
