Windows 10: Set File Association with .reg File
Set File Association with .reg File
i have a problem with File Associations in Windows (Build 1607).
I want to set a File Association for .pdf so that i can start .pdf files with Adobe Acrobat Reader DC and not with Microsoft Edge (default).
It is possible if i change it over System -> Default Apps but i need to do it with a batch file
If i change the settings on
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\Roaming\OpenWith\FileExts\.pdf Progid ---> AcroExch.Document.DC
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.pdf\UserChoice Progid ---> AcroExch.Document.DC
it don't work...pdf files always open with edge...
Anyone has an idea or can post a script to do that?
Sorry, why do you need to do it with a script?
Could you perhaps say what issue you are seeing?
Note you cannot set defaults from within a program. Must be set using Settings, Control panel or via Open With.
I have Sumatra pdf viewer as my default, was before the upgrade, was after.
I have noted a few people having difficulty with this. Do you feel you need to repeatedly need to set this association?

File assoc resets
One reason to use a .reg file is so we can one-click restore our custom settings after Windows capriciously decides to reset it to MS default Apps. Then instead of trying to remember where/what/how we set the association, we can just click our .reg file and have it all back as we customized... until the next time Windows resets defaults. This is exemplified by a bug of the recent Anniversary update... for some users ...suddenly they found a bunch of third party programs disassociated and MS Apps popping up instead. Annoying!
I'm using/assigning an old Microsoft .hlp file viewer... rather than have the winhlp32.exe stub send me to an Error webpage that MS so kindly throws at us now. It's tedious to go re-associate multiple times. It's easier to customize, then Export the association registry branch/twig/leaf... and later, when needed, double-click that .reg to re-reset back to our customizations. I'm not sure about the original poster's purpose, but I don't have the patience to fight MS re-defaulting... or look for the cause since it worked just fine before Anniversary and their rude resettings. Got to show off the new apps somehow.
Sorry, but resetting lots of file associations isn't trivial. I discovered a supposed fix to stop further resettings of music/photos/Edge/etc... seems to work ...until I lost the .hlp customization, which may be a different matter, but exporting a .reg would make recovery simple.
That looks interesting... have to remember to keep it updated after user customization and app installs, perhaps.
Will try it. Thanks!
Hello, I use Notepad++ to edit Python files which have the file extension .py such as "sample.py"
I would like to set Notepad++ as the default program to open .py files.
When I open a .py file I get the popup asking me which file I want to use...
I have Photoshop CS4 along with Camera Raw installed as well as Adobe Acrobat 9.5. Everytime I try to open a .NEF file Windows tries to open it in Acrobat 9.5. Naturally it cannot. When I go to the file associations Photoshop CS4 is not an option....
Some programs on the pc were not installed with the installer - they are portable zip files, I unziped them into a folder, made a shortcut to the desktop and they work fine for me. They are not listed in the 'installed programs' list.
I use files with an SCR extension to store text data. For me SCR means script.
I would like it so that when I double-click on this file, that it opens with notepad (or something similar).
But this file is registered as a screen saver. And...
I double clicked on xxx.jpg and LibreOffice opened. I wanted to change the program to IrfanView. I went in through Start > search > associations.
How could they screw that up ?
