How to force Win10 to install fonts in C:\Windows\Fonts?

Question

Formerly I copied a ttf-file to C:\\Windows\\Fonts, clicked the file to display the font, then clicked on [Install] and everything was fine.

When I do this procedure now

Answer 1

In the C:\Users\MyName\AppData\Local\Microsoft\Windows\Fonts directory right click on your font file and choose "Install for all users" (translated). A prompt will show up, telling that the font is already installed. Still click "Yes". The font will then be copied to %WINDIR%/Fonts.

One might think that the font file in C:\Users\MyName\AppData\Local\Microsoft\Windows\Fonts is not needed any more and can be deleted. But when you try, a message pops up, telling that the action could not be finished as the file is opened in System. - So we just have another copy of the file.
