    How to Unassociate a File Extension Type in Vista and Windows 7

    information   Information
    This will show you how to set a file extension to be associated with nothing for all users instead of some default program without having to delete the file extension unless you wanted to.

    Note   Note
    This is a standalone EXE program that does not install to your computer.

    Here's How:
    1. Download the free unassoc.zip file and save it to your desktop.

    2. Right click on unassoc.zip (On Desktop) and click Open.

    3. Extract both files to the desktop. (See screenshot below)

    4. Click on the Unassoc.exe icon to run the program.
    NOTE: I would recommend that you put these two files in a new folder and save them in your C:\Program Files folder, then make a shortcut for the Unassoc.exe to use.

    Re: Unassociate File Extention Type

    Hi, I have been trying desperately for 3 hours to remove the association of the file type .INS from the program "Inspiration" (Document Mapping) so that I can run an .INS file as an "install shield script" file. I tried your tutorial and, sure enough, in the control panel, the ".INS" file type is no longer associated with Inspiration. However, when I look at my downloaded copy of a new program that I want to install that includes the .INS file type, it is still associated with Inspiration! It is EVIL! Can you help me? Thanks!

    Re: Unassociate File Extention Type

    Sorry, me again, I just realized that I deleted the file extension instead of unassociating it. Is there any way I can fix this??? Thanks, --e.

    Hi Elisabeth,

    Welcome to Vista Forums.

    If you installed a program that added the .INS extension, then you can reinstall it to add it back so you can unassociate it.

    You can also right click on the .INS file and use Open With to select a EXE program to use to open it with.

    Default Programs

    Hope this helps,
    Shawn

    When I run the program and find the file I want to unassociate the Remove file association (User) is grayed out. What else can I do do unassociate.

    .001 from 7-zip I didn't want to always open with that program.

    .001 from 7-Zip? I do not see a file extension listed for that in 7-Zip.


    Anyways, you can unassociate it by:
