    Default Windows 10 changes default program

    Windows 10 recently reported that an application (presumably Irfanview) had caused a problem with default files and that the default program for viewing images had been reset to Photo viewer. This is very annoying behaviour but typical of the controlling mentality that seems to pervade Windows 10.
    Is there anything that can be done about this?

    Try using the Extensions tab in IrfvanView Settings to set it as the default for the images that you want to open in it.

    I would try, what Bhikkhu Pesala suggested, with launching IV as administrator.

    Basically if you use a IV shortcut on the Taskbar, right click it, select Properties. Click on Advanced... then tick 'Run as administrator'.

    Do this for any other shortcuts you may have on the desktop, etc.

    You may wish to also click on the 'Run this program as an administrator' in the Compatibility tab of the shortcut properties.

    Please note, there was a massive update to Windows 10 recently that reset the OS file associations with images. So any future updates may very well override your settings. Still, easy to change them back.

    This happened on my laptop running Windows 10 Pro. The fix is easy with no need to go through "the backdoor" - registry hacks, etc.

    Click Start, type: "Default Apps Settings".

    Scroll to and click on: "Photo Viewer" and select Irfanview from the list.

    Click the X in the top right corner of this window. Locate and double click some photo files *.jpg or other picture files and test it.

    IrfanView 32 user - I use the Kadmos plug-in for OCR (v4.4y 12-19-2013). I use a win8 ASUS machine upgraded to win10 during the free win10 upgrade trial.

    I upgraded yesterday to 4.51 from 4.42. File associations are not sticking when set in IrfanView 32, either during the installation or using the options screen.

    Here are some things I tried.
    1. Uninstalled. Re-installed with "run as administrator". -- Didn't fix the associations issue. IrfanView doesn't even show as a selection in "Default Apps".
    2. Used "dsim.exe" to export associations as xml. Updated the xml with the correct associations, and imported with "dsim.exe". -- Didn't fix the associations issue. IrfanView doesn't even show as a selection in "Default Apps".
    3. Uninstalled. Re-installed with the "MS Store" by searching for "IrfanView 32". This installed 4.50 under c:\program files\WindowsApps\, which is secured. -- This approach allowed the default app for photos to be changed, which I did.

    I didn't try installing the plug-ins or Kadmos yet. I'll post back with those results (or problems).

    I have two of the same systems, as described in my original post. One system is default out of the box; the other I wiped and re-installed. During the Win10 april upgrade, which happened a few weekends ago, the win10 file associations process was changed.

    Irfanview 32 4.51 works fine under the freshly installed system.

    The "default" system gets the win 1709 build. So I did the above by installing from the MS store. MS installs it under WinowsApps, which is owned by the installer, and cannot be accessed. It became unbearable to try to get it working properly with irfanview 4.50, which is what the MS store installed.

    So I uninstalled, and re-installed the 64-bit 4.51 on the win 1709 build machine. This at least installed in a "typical" place under "program files". I unzipped the plugins and copied those to the plugins folder.

    I tried setting associations during installation and again using the options. Neither works. It is not possible to change the default app under "settings" because irfaniview doesn't even show. The new april-build win10 doesn't allow for browsing to default apps.

    Let me know if these recent posts should maybe moved to another topic.

    Please also let me know if this is "fixable".

    Before you do anything, update to Windows 10 1803, or you might have to do it all again after updating.

    Run as administrator, then set the extensions in Settings/Properties.

    Once you have fixed it, IrfanView will show up in Default Apps.

    Thanks for your response. I am thinking it is corrupted file system permissions tbh. There's other apps misbehaving. I am going to do a re-install of win10. I'll post back with my notes.

    Thanks again. iv is really cool sw that I've used for years. First problem I ever had.
