I wanted to change default icons for .py .cpp .c using FileTypeMan. But after that, the icons of all of them became the same because the default app for these extensions was vscode. I tried to fix it using regedit (How to Assign a Custom Icon to a File Type) but nothing has changed.

I would appreciate any help to change this to default icons or separated icons for each file type.
