Update:
There is a PowerShell module called Carbon which provides this and a
whole lot more. It can be installed in numerous ways, including via
Chocolatey. Here's what I am using:
choco install -y Carbon
Import-Module Carbon
Grant-CPrivilege -Identity myuser -Privilege SeCreateSymbolicLinkPrivilege
See <https://get-carbon.org/Grant-Privilege.html> The command name I
used above is now the preferred spelling, although that's not reflected
on the manual page.
