Icons of Excel disappeared

[Abel D.]

I checked my second system in my work (before update 1903) and I'm dumb now. There I have:
HKEY_CLASSES_ROOT\.jpg = IrfanView.jpg
and in
HKEY_CLASSES_ROOT\IrfanView.jpg\DefaultIcon = C:\Program Files (x86)\IrfanView\i_view32.exe,0

but association of jpg files in Windows 10 and in TC is with Photoviewer and icon is Photoviewer ini Windows 10 AND TC.

So, it looks like registry icon association doesn't work this way?

EDIT: I tried to find out, and I changed HKEY_CLASSES_ROOT\.jpg to IrfanView.jpg (and restarted Windows 10 of course)
Now I have IrfanView icon in Explorer and TC

In Windows 10 in "Default applications" I have none (choose default)

To be more fun, png files are now associated with Photoviewer, but HKEY_CLASSES_ROOT\.png is IrfanView.png
and HKEY_CLASSES_ROOT\IrfanView.png\DefaultIcon is C:\Program Files\IrfanView\i_view64.exe,0
Icon for png is Photoviewer in Explorer and white icon in TC.

EDIT 2: I restored previous version of registry, because I couldn't set the default graphic files for Photoviewer in Windows. I choosed Photoviewer and nothing happened. Tried to do it another way as well - right click on jpg file, choosed "Choose another application", marked "Always choose" and... nothing as well.
Frustrating, so I restored registry. I prefer to have white icon in TC only...

After finding [HKEY_CLASSES_ROOT\.jpg] in regedit I have: https://i.imgur.com/q7tHhUZ.jpg

I have NEVER seen such an association before.

I have such an "Applications\photoviewer.dll" accociation for .gif files but under WIndows 7 - in Windows 10 I have one of those unreadable "App...." associations - In Windows 10 .gif files are opened with PhotoViewer, but I do not have the PhotoViewer icon (just as Abel D. doesn't have for .jpg).

In Explorer under Windows I do see a PhotoViewer icon for GIF files but not the original icon: from C:\Windows\System32\imageres.dll: http://madsenworld.dk/tcmd/gifIcon.png - but in stead i see the icon embedded in "C:\Program Files\Windows Photo Viewer\PhotoViewer.dll": http://madsenworld.dk/tcmd/PhotoViewerIcon.png (which Abel D. also have for .jpg)

Here is what I see in Windows 10 in Explorer and TC:
http://madsenworld.dk/tcmd/win10explorerIcons.png
http://madsenworld.dk/tcmd/win10tcIcons.png

And here is what I see in Windows 7 in Explorer and TC:
http://madsenworld.dk/tcmd/win7explorerIcons.png
http://madsenworld.dk/tcmd/win7tcIcons.png

According to the Regsitry for both Win10 and Win 7 the default icons for:
giffile is: %SystemRoot%\System32\imageres.dll,-71 = http://madsenworld.dk/tcmd/gifIcon.png
jpegfile is: %SystemRoot%\System32\imageres.dll,-72 = http://madsenworld.dk/tcmd/jpgIcon.png
pngfile is: %SystemRoot%\System32\imageres.dll,-83 = http://madsenworld.dk/tcmd/pngIcon.png
paint.Picture (bmp)is: %SystemRoot%\System32\imageres.dll,-70 = http://madsenworld.dk/tcmd/bmpIcon.png

---------

You can try this:
1. Download http://madsenworld.dk/tcmd/jpegfile.reg
2. Make a backup of:
[HKEY_CLASSES_ROOT\jpegfile]
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\jpegfile]
3. Double click on the downloaded jpegfile.reg file to update your Registry.
4. Put the cursor on a jpg file in TC.
5. Chose "File" -> "Associate With...".
6. Find and click on the entry: JPEG Image (C:\WINDOWS\System32\rundll32.exe "C:\Program Files\Windows Photo Viewer\PhotoViewer.dll", ImageView_Fullscreen %1)
7. Click OK.
8. double click on a jpg file, you might have to re-associate the file to PhotoViewer if asked.

If that doesn't work try this:
1. Download http://madsenworld.dk/tcmd/photoviewer_fileassoc.reg
2. Nothing to backup
3-5: As above.
6: Find and click on the entry: PhotoViewer.FileAssoc.Jpeg (C:\windows\System32\rundll32.exe "C:\Program Files\Windows Photo Viewer\PhotoViewer.dll", ImageView_Fullscreen %1)
7-8: As above.

@Abel D.
Associations like ".jpg -> jpegfile" are one of oldest Windows features. There have been other ways of association introduced later, f.e. shell extensions with registered classes (see HKEY_ROOT\CLSID branch), which have higher priority in Windows Explorer. And you can also register extensions in TC and this association has the highest priority in TC.

@petermad
In Windows 8+ those associations with App-IDs (probably encoded with Base64) for apps from Windows Store create another level of priority. What is more, some associations seem to be somehow protected. For example, some Windows 10 builds force association PDF with Edge. I was trying to change this association to SumatraPDF - installed as a desktop program and as an app from Windows Store - and both versions failed.

It works! Thank you! I did it the same for gif files and it works as well first, but today it doesn't work. Weird.
I tried to do it for jpeg file, but it doesn't work.
I know it's a long shot, but if I would knew how to do it for other graphic files (gif, png, jpeg), I would be grateful as well.

In Windows 10 in "Default applications" for graphic files I have none (choose default), but it doesn't matter, because in Explorer graphic files open with Photoviewer and icons are right.

some Windows 10 builds force association PDF with Edge. I was trying to change this association to SumatraPDF - installed as a desktop program and as an app from Windows Store - and both versions failed.

Hmm - I have had no trouble associating .pdf with Adobe Acrobat Reader in both the 1809 and the 1903 version of Windows 10.

Actually I haven't had any problems re-assigning most other file types to "normal" desktop applications in stead of those extremely slow Metro Apps (at least they are slow on the old laptop that I use for testing Windows 10 - I still cannot see myself using Windows 10 as a serious work environment - sad that support for Win 7 stops next year )

But what Adobe Reader version?

I don't remember details in my case, but I'm pretty sure I have SumatraPDF 64-bit installed. So it was possibly some Insider build rather then well known bug caused by KB4462919:
https://support.microsoft.com/en-us/help/4462919/windows-10-update-kb4462919

I still cannot see myself using Windows 10 as a serious work environment - sad that support for Win 7 stops next year )

Nothing more to add…

[petermad]

But what Adobe Reader version?

It's Adobe Acrobat Reader DC version 2019.012.20035 that I am currently ruinneing (32bit)

Thank you very much.

I am using Total Commander Ultima Prime 7.8 with latest Windows 10 and I cannot get working file association with it to jpg files. I am using Honeyview for images and TCUP was always asking for default program.

The jpegfile.reg solved my problem.

Hello,
since I updated to 9.51, I have a similar problem. At one (!) of my computers the icon in the file list windows shows only as a white rectagle with a little bonded corner, like the *.txt icon but without the lines.
In my case, it is the *.mp4 extension. I use VLC to open it, and the icon in the explorer is shown correctly.
I couldn't find any *.ini or *.icl file on my win10 computers (winver 20H2) that might be editable or comparable with the other computer.
Reinstalling TC and VLC doesn't make any change.
Any suggestions?
Thank you in advance, stay healthy

Winneone: Do other icons show correctly at TC on this computer?

After some Win10 update, the icons of Excel disappeared from TC (there are just the white ones).

Hi
I have Windows 11 and had the same problem in Total Commander.
In this post I will focus on the Excel application icons, but the same mechanism also worked for me for other Office applications, e.g. Word.

Let's look at the problem before solving it. We see here 20 files, each of which has an extension that should be assigned to the Excel application. You can see that a white paper icon is displayed for several file types. I'll describe how I fixed it in a moment.
Image: https://i.imgur.com/f0t4D1P.png

I found a simple way to fix it for me.
Go to Windows 11 Settings, then go to Application -> Default application. Then search for the Excel app. Click Excel app item.
You will see a list of file extensions that are currently assigned to the Excel application.

In my case, at the Windows level, all file extension assignments to the Excel application were correct. The only problem was displaying icons for these registered file types in Total Commander.

In my case, for example, the XLSB file type was incorrectly displayed in TC.

So (in Windows Settings) click this particular XLSB item - see my screenshot:
Image: https://i.imgur.com/tPLOUGS.png

The screenshot shows that at the Windows level this file extension is correctly assigned to the Excel application.
But anyway, let's double-click on the Excel application.
After this action (and after restarting Total Commander), the icon for the XLSB file type is displayed correctly in TC
See the screenshot after this action:

I hope this helps some of you. It helped me.

It would be nice if I could somehow detect this new file association state. However, the problem does not happen here, neither on Windows 10 nor on Windows 11. I'm using LibreOffice instead of MS Office, so I guess that Microsoft is doing something strange which isn't documented yet.

That's why I need information about the misbehaving file association to find a solution.
If you have this problem and haven't fixed it yet, then please use my tool RegistryInfo with the affected extension and post the results here:
