As you might know, on Windows 10 there are no way to pin any app or link to start by default as it was before on Windows 7
Actually, to pin some app or some internal/external link is very simple. You have to go to the windows directory:
C:\ProgramData\Microsoft\Windows\Start Menu\Programs
- Then, put any app link to any location within this directory
- Through the start menu search the link by its name
- PIN is to start menu from context menu (mouse right click on app/link icon)
