Windows system suddenly unable to set Notepad as the default application for *.md files?
Today, I suddenly cannot open *.md files directly with Notepad by double-clicking them. The system prompts me to select an application, but I cannot select Notepad. I have tried modifying the file association through the default app settings, but it did not work. Currently, I can only open files manually through the Notepad menu, which is extremely inconvenient. I need your help.

It sounds like the file association for .md files (Markdown files) has been broken or corrupted. Since you've already tried changing the default app via system settings without success.
