How do you create a new symlink in windows 10 using powershell (not mklink.exe)?

1. Start powershell as admin
2. You need to know 1) the path to target of the link 2) path to location where you want the link 3) the name you want to use to refer to the link.
3. PS C:\> new-item -itemtype symboliclink -path <path to location> -name <the name> -value <path to target>

Example: If you're in c:\drivers\AMD and you want to link in f:\driver\olddrivers, then you would go

PS C:\> new-item -itemtype symboliclink -path . -name OldDrivers -value f:\driver\olddrivers

And wind up with a symlink path of c:\driver\AMD\OldDrivers

Use the New-Item cmdlet and specify the appropriate ItemType of SymbolicLink, HardLink, or Junction. Note that these are only available from PowerShell 5.1 or newer.
