 WinRM user rights

In order to connect remotely, it is necessary to be part of the Administrators group (or Remote Management Users for Windows 2012 and above) either by being directly connected with the correct account (for example via a domain administrator user) or by using authenticating as an administrator via the Credential parameter.

On Windows 2012 and later, it is necessary to add a registry key on the remote computer so that the Administrators and Remote Management Users groups have the right to connect via Remote Powershell:

On the host : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system

You must add the key DWord : LocalAccountTokenFilterPolicy with the value 1.
