Hello, i'm wondering if it is possible to change a open with option back to unknown application on some files. i accidentally clicked open with the picture opener and its stuck on it now. how can i revert this? step by step if possible.

Thank you.

Go to Default Programs in Control Panel open it, select Set your Default Programs. First off you need to know the extension of this file you do not want any program to open, example, jpeg, gif..etc.. Select each program that can open this file and uncheck that extension for it, then would be back to unknown.

basically for the exact situation here, i downloaded a sky im mod and i accidentally put it so it would open the file with windows photo viewer from what i see the files extension is .dds but when i do as you say, i don't see a option that is check marked for a extension such as dds, is it possible for someone to help me via teamviewer? if not then does this recent information change the steps in anyway?

Skyrim is a PC game how did you make this file open with which is called Photos now in Windows 10, said you checked defaults for this viewer and do not see it ? Not familiar with this type of file, but believe should not be opened with Photos. I know nobody here that does team viewer for forum help.

There are viewers for this, example here and tells you what the file is
Here is another explanation

i want it to go back to the blank page again like i showed in the last picture.



Sorry for the bother...

Thank you.

All i see from this is the extraction of a compressed file with WinRAR. What other picture ?

what i mean to say that its just a blank paper and not the photo viewer like the first two pics

Starting to understand reasons for this viewer with Skyrim, maybe need another viewer for it unless game came with it. Is this what you are trying to do anyway, view the .dds files ?
As far as eliminating Photo viewer from using it should be done in Default Programs as suggested, if associated with it, then would be on the list under that viewer, Photos.

listen man.. this is as close as i can get but it only gives me an option to change it into another known program.
