Fix Windows 10/11 Icons Not Showing Up / Working as Expected

Behold, a bug!
  1. Run IE4uinit
  2. Delete IconCache files
  3. Remove the registry keys related to the file type and then have Windows rebuild it.

If neither of those fixes work, here is another fix that has worked for me several times…

This method involves deleting the file type, then letting Windows rebuild the needed registry keys. Nothing major, and worst case we can always undo the change.

  • Open the Registry Editor
  • Navigate to HKEY_CLASSES_ROOT\.xyz where .xyz is the extension you want to fix
  • Click on that key — .xyz — then click File > Export > TypeBackup_xyz > press enter
  • That will make a backup — if for some reason something goes wrong, navigate to this file, run it, and it will restore the registry key
  • Right-click on the .xyz key (ensure you have selected the .xyz key and NOT anything else), then hit Delete, then yes
  • Now navigate to (you can just copy-paste this into the navigation bar)
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FileExts
  • Under the FileExts key you will have a list of extensions as subkeys
  • Find your extension, such as
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.xyz
  • Click on that key — .xyz — then click File > Export > TypeBackup2_xyz > press enter
  • Right-click on the .xyz key (ensure you have selected the .xyz key and NOT anything else), then hit Delete, then yes
  • Close out of all Windows except for your web browser
  • Open a folder with a file that ends in .xyz and open it, it will ask what program to use to open .xyz files
  • Select a program, hit OK
  • That will force Windows to rebuild the registry keys for that file extension
