Removing the "Open File - Security Warning" in windows 8?

  • CarlG

    I like to study a lot of code from various sources from around the internet, and a big part of that involves downloading and opening the files to view the source code.

    Now every time I try to open these files it gives me a prompt to make sure that the file is from a valid source and that I trust it to run.

    There are many answers on this site, that deal with this issue on the following OS; Vista, XP and 7, but I couldn't find one for 8, and I could not get any of the others to work!

    Could someone please tell me how to disable this very annoying feature for someone like myself?

    Add a system environmental variable SEE_MASK_NOZONECHECKS and set the value to 1.

    Make sure it's a system level variable or it will go away on reboot.

    You should be able to resolve this by seting up trusted sites properly?

    Other wise, try this.

    Close internet explorer
    Open up a cmd prompt
    cd "\Program Files\Internet Explorer"

    This allows the file to open directly from Internet Explorer, however the file on disk will still be 'blocked'.

    One other solution is to open the files directly from your text reader, i.e Notepad++. It is explorer that is enforcing the warning.

    See: "This file came from another computer..." - how can I unblock all the files in a folder without having to unblock them individually?

    I had a very similar problem on my brand new Windows 8 laptop. The desktop icons (.lnk)'s gave the same "open file security warning". Don't know why or what happened but what a pain. I finally found a solution, at least for the desktop icons doing it. I didn't want to fix it with changes to IE10 settings, like some suggest, because that just seemed risky.

    This worked for me:

    1. Press Windows button + X to open the Tools menu
    2. Select: Command Prompt (admin) to open the black DOS window with C:\Windows\system32\>
    3. Enter

      cd \Users

      The display now says C:\Users>

    4. Enter (replacing "YourName" with your username)

      cd YourName 

      The display now says C:\Users\YourName>

    5. Enter

      cd Favorites 

      The display now says C:\Users\YourName\Favorites>

    6. Enter

      cd Desktop 

      The display now says C:\Users\YourName\Favorites\Desktop>

    7. Type and enter:

      C:\Users\YourName\Favorites\Desktop>ICACLS *.LNK /L /SETINTEGRITYLEVEL MED

    All the links on your desktop should come up as:

    processed file: whatever.lnk
    successfully processed 10 files; Failed processed 0 files.

    Sorry for the long hand on the DOS commands, I remember them from back in the day but, this is laid out for anyone to easily follow.

    How do i disable this Open File - Security Warning dialog box? everything i find involves adding ip's to trusted sites etc. but this application is installed locally. I've already unblocked the exe from the properties window, however that didn't help

    Try right clicking the exe file and select properties.

    If there is an unblock button on the General tab click that and it shouldn't bother you again

    If you are using IE 7/8, Go to Tools / Internet Options / Security and click on the local Intranet Icon. Then, click the sites button. Make sure "Automatically detect Intranet Network" is unchecked and the following items are checked, "Include all lical (intranet) sites not listed in other zones", Include all sites that bypass the proxy server", and "Include all network paths (UNC's)".

    I would only do this is the file you are try to access / execute is located on your local file server and unblocking the file is not working. I used to have this problem with our ERP application who's .exe file resided on our file server. After upgrading our clients web browsers from IE6 to IE 7 or 8 we started to get the same error message. The above steps are what fixed it.
