Windows Notepad Icons Become White Blank Looking Document Page

In Windows 10, files and shortcuts that had a Notepad icon changed and the new icon appeared to be a blank white document page. For my computer, this was notice around 01/10/21. The “Site” (https://www.winhelponline.com/blog/change-default-icon-file-type-windows/) was helpful used in finding a resolution. The resolution fixing the problem was to edit the registry value from HKEY_CLASSES_ROOT\txtfile\DefaultIcon\%SystemRoot%\system32\imageres.dll,-102 to %SystemRoot%\system32\notepad.exe,-2. The DefaultIcon and the file it is located in have changed with versions of Windows. In some of the newer versions of the files referenced for the default icon, the icon referenced was not present. Associating applications to file extensions in Windows 10 settings is immediate but is not necessarily reflected in some registry key values after a registry refresh or reboot. The value in the key HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.txt\UserChoice\ProgId\ on my computer was textfile. This value was txtfile on the “Site”. This entry could not be edited because of permissions so it could not have been inadvertently changed during the attempts to fix the problem. The permissions were changed and it was edited to txtfile. A more detailed discussion is at (Link->)White Icon Blog Page
