You can use either mklink (cmd built-in) or junction (from Windows SysInternals, which is part of Microsoft) in Windows 10 to create junctions.
junction can also list junctions and determine if a file is a junction unlike mklink.
mklink is an internal command only available within a cmd shell.
By default Administrator privileges are required to create symbolic links.
It can also be granted to other users. The security setting "Create symbolic links" can be granted at:
